Selfie

Should have taken a picture of his cock and balls and made it his screen saver.

When I was young and even more of a dick than I am today, at parties, if there was a camera lying around somewhere, hopefully belonging to the parents or the sister, I would sneak in to the bathroom with it and snap some nice closeups of my dick. This was back in the film days and they would have to go to the local printshop for the prints and negatives. I would giggle thinking of the reaction both from the guys in the printshop and also when they opened the envelope, hopefully with some people around for extra effect

okay, this IS funny.

wanna take it to god-level?

Gently put a book about Chinese algebra or astro physics in his hands while he's out and wait for him to wake up.
