These are gold, I liked the one about Patrick Stewart too, anyone who buys a game just for the celebrity talent included (*cough* 50 cent *cough*)is a tool.
Most of the ones I've heard are already mentioned, but here's a story none of you will have heard before.
I was doing playthrough of metal gear solid and we got to the part where you put the controller on the floor with psycho mantis. My friends 11 year old cousin had just walked in and she then proceeded to freak out at the 'pocessed' pad, "make it stop.... MAKE IT STOP! Dx" evil I know, but it was funny to see gaming ignorance personified in that one moment I'm almost sorry to admit hehe.
