What is the funniest thing you've ever seen someone do while playing a video game?

Fun question!

Ok, this is going to be a bit 'weird', so I'm not going to mention any names incase he stumbles upon this one day... Actually, I should probably answer anonymously too just to be on the safe side!

But a bunch of us used to play first person shooters like Counter Strike online during high school, and one of my friends had a ritual that he would perform to help improve his performance.

Essentially, it involved sitting in his computer chair without a shirt on, cutting a lemon in half, and rubbing each half on his nipples.
