Yeah my players didn't find it so funny at the time.  They now look back at it with the same amount of humor as Morningstar Leg.  Now THAT was a funny story.  I'll get around to telling it eventually.

One of mine isn't truly a story, but something just kinda funny when thinking about it.  I play the D&D Essentials for 4.0 on Wednesday nights, and we have a couple tables' worth of both veteran players and new players.  One of our players has this fascination with building characters that never focus on the stats they should focus on for their powers.  Of course, this means the healer that he wants to build has very little healing ability... and often is in negative hit points before anyone else...

When I was in college, we had a guy who got put under a love spell and accidentally fell in love with his horse.  The party had to take extra precautions to make sure he didn't go off alone with the horse...because at every opportune moment, he would tell the DM he is going to take the horse out back to have some alone time.

In an all-elven game I'm in(drow, elf, half-elf, and eladrin), two members of the party was asking witnesses to a murder about it... then apparently they decided to kill the witnesses...

There's a story in my Wednesday night game about this one time before I was there when they faced a Mindflayer. The Cleric and the Wizard apparently both spent pretty much the entire fight dominated.

... since then, the Cleric has acquired an immunity to dominate, and the Wizard... hasn't... and now has a piece of the Mindflayer god living in his head.

Oh, now, what a lovely thing to have stuck there...

Yeah... he needed some rare potion ingredients and that was the price...

All I had to give up was all memory (ALL memory - even the memories that the other party members had) of an agreement that I'd had with said Wizard for two minutes of silence from him. Whenever I asked. In exchange for some more vaguely un-useful information about how to obtain my Epic Destiny...

Grant can tell you what he did in my game.  The fighter had a cursed sword that had intelligence and was a good bonus but forced the user to always use it as the preferred weapon and never let it go.  When the fighter died, Grant's character (a cleric) picked up the sword, forgetting its purpose.  He then had to use a sword (which he couldn't do as a cleric).  But things got worse when the fighter was resurrected and came looking for his sword.  They had been friends and companions, but the curse of the sword was upon them both, so he basically beat up Grant's character and took it from him.  It was pretty funny. :)

Hehe. Our wizard has a cursed sword. It's literally attached to his hand. It also gives him some kind of penalty to... something. I'm not really sure what though. It will stop being cursed when we beat the dragon that put it there...

When I was running two groups, they were on two separate missions:

The first had to sneak in and investigate and kill a group that was meeting in secret after listening in on their meeting.

The second group had a mission of infiltrating the group, being invited to the meeting and sitting through the meeting, finding out who was friend or foe, and killing the dangerous foes.

Since this was done online through two separate groups, it worked out perfectly.

The first group prematurely started attacking while the second group was dressed as the supposed "enemies."  They didn't know each other either, so chaos ensued, with characters of one group attacking both the bad groups and the characters from the other party, who found their meeting suddenly beset upon by violent intruders...

Haha! That's cruel Heath! Cruel, but hilarious!

I was running a campaign where societally magic was less common, but I still allowed the players to function as normally within the rules.

Since we'd been playing together for some time at this point, and I knew the group would handle it responsibly, I let the players test some of the 3rd edition expanded rules, provided they had a hard copy they could bring with them to sessions.

As a result, a friend of mine who had the savage species 3rd edition expansion wanted to play a half satyr/quardos demon mix. With good reason I warned him in advance that either of these creatures would be fairly uncommon in my setting, and he may encounter some difficulties as a result. But determined, and interested, he decided to play anyway.

As an interesting quirk to the combination he decided to play a true neutral character---but play it as though he were a split personality between a lawful good character, and a chaotic evil one. I was a bit skeptical, but given I'd warned him in advance, I let him go with it.

It was a tricky balance, as a character, but he played it off well. Switching between the lawful good satyr-side, and the chaotic evil demon, however a four armed satyr stuck out, and his evil side got into some serious shenanigans, involving local murders.

Needless to say, it was fairly easy to run sessions for this group because they provided their own drama for me. But the local trouble eventually got the better of the character, because the lawful good satyr side kept wanting to turn himself in, in utter shame and remorse, and the chaotic evil demon kept killing people to try and flee for his life.

The rest of the party decided they would have to put the demon down, in what remains to this day one of my favorite scenes of roleplay, and has actually resurfaced as mythology in my campaign setting a couple of times.

The demon, trying to escape boarded a ship as a stowaway, but was found shortly after leaving port. He ended up killing several of the crew, and lighting the ship on fire in the ensuing chaos.

The other PCs were trying to track him down, and when the boat caught on fire in the distance they figured it out pretty quickly. One of the other PCs was a druid, and shape-changed into a fish to swim out there. It took a bit, but the quadros was still distracted by the boatmen, so it worked out.

The fish hops on board, and without missing a beat calls lightning down from the sky onto the Quadros. Down on HP from the battle, it was enough to put him down.

So as I said, my world is fairly low on the magic scale, so having a demon rampage on the boat only to be taken down by a fish calling down lightning isn't something you see everyday. The surviving fishermen revere that fish as an avatar of the gods, and worship him as a minor deity to this day.

Ah good times.

You are a god.  That is awesome!

>_> In that world, I'm all the gods. Haha. But that druid character, of my friends is certainly revered in some circles now.

What did the player do who was playing the satyr/demon?

That made me laugh. I need a good laugh in the mornings. :D

The quadros/satyr knew it was coming and agreed that the other players had to put him down. He enjoyed the character, but he wasn't upset that the others had to kill him. So when the character died, he just rolled up a new one.

Last week I was DMing and my players for some reason spent almost all of their money on horses when the next part of their journey would be by boat.  They bought passage on the largest boat they could find.  About halfway downriver they were attacked by Bullywugs who were stabbing holes in the ship's hull causing it to start to sink.  They freaked about their horses and said they would jump off and swim to shore.  I informed them that there were 10 to 15 foot cliffs on either side of the river.

They then began to argue with me about river formations and how the river current wasn't fast enough to dig its path through so much rock and would instead have made a path through the nearby soil the trees were in.  They said that the reason the nearby path wasn't right alongside the river (which I had mentioned earlier) was because of yearly flooding that would have washed it away.  They told me that if I wanted to make an even somewhat realistic world then those cliffs should not be there.  I smiled and said something along the lines of, "About 200 years ago a wizard was chasing a ship down this river and summoned a water element to catch it.  It ended up going so fast along the river that it dug out the cliffs."

This was met with more arguments that I simply answered with "A wizard did it."  After an annoying half hour of this though I realized they just wanted there horses to live.  They ended up just crashing the ship into the cliff and running away so the entire argument had been pointless.

I once had a group that walked into a medusa's lair and all got turned into stone.  That ended the campaign real fast.

I once had a party of adventurers come across a town turned to stone, but rather than the traditional monsters that could have caused the ruckus, instead I had some scooby-doo villains with boots that made their tracks look like basilisk tracks, and a ring of flesh to stone.

And they would have gotten away with it too if it weren't for those pesky PCs.

Sounds like the adventure I've run twice because it works so well.  The group is told there are vampires drinking the blood of livestock and a couple human victims, and they live in a cave on the hill.  The adventurers get decked out with silver and magic and vampire fighting tools.  Turns out that there is only a giant spider and a harpy making all the ruckus up there, and the blood was being sucked by a herd (?) of stirges.  No undead.

I just had my planned reoccurring villain killed off in his first combat encounter with the PCs...

Something too amusing to NOT share happened at my D&D game tonight, and I feel like you all are an audience who can appreciate the awesomeness of it.

First, the setup: Our party of epic-level (27) characters are currently traveling the path of death in order to find an evil dragon and slay it. We are at the sixth level of the path, which was apparently supposed to be an extended rest-equivalent stage... but the dragon we're chasing trapped it. Because of this we ended up having to fight a dracolich (not fun), and now we have to reincorporate our selves-of-the-past by fighting them.

My character is a monk, which means that I have pretty solid defenses all around... usually (AC - 42/Fort - 38/Ref - 41/Will - 40). Unfortunately, my opposite in this particular fight has an At-Will ability to Dominate me (and presumably anyone else, she's just never used it on anyone but me), and the DM can't seem to roll lower than a 50 for that particular move.

Now begins the amusing-awesomeness: I finally made a save against the Domination, but my doppelganger's turn came before my next one, so of course she tried to hit me with it again. Our Artificer, awesome guy that he is, used an ability of his to take the effect upon himself instead, becoming Dominated in my place. Since I was the closest target, the doppelganger subsequently told him to try and hit me. So he tried the way he normally does. First, he rolled a d20 to "predict" the turn (an ability attached to his Epic Destiny - Sage of Ages allows him to pre-roll a die, and substitute it for any d20 roll that he makes during the turn), then rolled a second die as his normal attack roll. The "prediction" die was a 1, the regular die was an 18. So what did he do? Switched in the 1 for the 18, of course, automatically going from a hit to a miss.

Truly that was the best use of his Sage of Ages prediction ever.

If he was trying to hit you wouldn't his character be forced to take the higher roll?

Nope. We go by the "if the DM doesn't complain, then you can do it" rule. And I think the wording of the power is such that it doesn't matter.
