*looks around fearfully, then hesitantly peeps in a tiny voice* ...One?

Ah. I'm with them. Think of me as an... intermediary.

How many of President Clark's minions does it take to change a light bulb?

Semi-interesting story:  Sometime between Season 1 and Season 2 of Babylon 5 I attended an event called BabCom in Birmingham.  Peter Jurassik was there, taking questions from the audience and doing a stand-up routine in full Londo Molari make-up.  One of the audience asked him "How many Centauri does it take to change a light bulb?"... the very joke that appears just above here.
Well J Michael Straczynski was there (the show's creator and main writer) and he must have thought it was funny, because Londo himself told the joke to Vir in an episode in about Season 4.

I was recently reminded of this, and was delighted to discover that it exists online.  Enjoy...
