Not you, ME!!!
Tadeusz, your attempts to cheer me up are nice, but you need to try harder at being stupid. Although most of my questionable actions are more of the 'rude like a 4chan troll'-type, I can easily best your worst decision ever. Case in point, you had some serious bad luck to get 2 '1' in a single roll, but my story involves not a single one. Admitting, it was my first actual game with dice, but even I should have known better than this:
I was playing a 'not very lovable rogue' and we were tasked by a priest to take an 'Evil Stone' to a forge to be destroyed with their 'holy hammer'. Sure enough, our first step was to get lost in the one and only woodland between us and our destination. This was partly on purpose, because we were expecting trouble if we just followed the road, but still not a big plus for our resume. We had to spend a night in the forest, but nothing big.
Next morging, my task was to scout ahead of the main party, and make sure we weren't amused. So when I see a group of knights riding down the road, my first mistake was to forget I had done nothing wrong yet and hide in the foliage. Not a big mistake, if these 'holy templar' had not been send to see what was taking us so long, and enforce our team if we were in trouble. They ride on ahead, and I just relay it to the team. When we finally do arrive at the forge, we find it to be suspiciously quiet for an iron-mill. So I get sent out to scout around the place and sure enough, just outside the main door, I find that group of knights, dead.
Now, rather than think about this being a hint of danger, my inner munchkin kicks in and I loot these guys from penny to underwear and report back to my party, loaded with 6 sets or armor: "Hey guys, there's some dead dudes over there. I think they got mugged, cause they don't even have a penny on them."
At this point our GM suggested a redo, because defiling a crime-scene is one thing, but selling your alibi, of "it was like that when I got there" to your own team of 4, who know you're playing a greedy thief, WHILST CARRYING THE OVER-ENCUMBERING EVIDENCE ON YOUR BACK, is just a little too much to expect.
