Who is the most annoying sidekick or partner you've wanted to shoot in the back and save the enemies the trouble? I wanted to restrict this to video games, but I haven't played enough co-op type games to make a big enough pool of idiot partners I want to kill.

My vote is Dum, I mean Dom, from Gears of War. This stupid m*therf*cker keeps running out and getting killed and I keep having to go save him to use him as fodder to distract the mobs while I pick them off. I've died so many times trying to revive this meathead, I can't f*cking stand it.
