I'm not to sure how this joke goes but i'll try.
Little Johnny is sitting in class one day when the teacher asks "can someone give me a ten letter word"
Little Johhny shouts back "masterbate"
The teacher replies "thats a mouthful"
Little Johnny without missing a beat "thats a blowjob and its only a seven letter word"
Pacman taught people to run around in dark rooms munching on pills while listening to repettive techno music and for that I somewhat idolise him.
