One of the only times I got detention in high school was when playing CS 1.6. It wasn't for playing the game, though - our class had done something good and as a reward we were allowed to goof off and play games that period.
But, a classmate had killed me several times in a row and was having a good laugh about it. I gave him a middle finger and then got back into the game.
At the end of the class, the teacher handed me a detention slip and then explained that he had been standing behind me watching my screen when I flipped the bird.
