My new roommate, Bill, had been a dick since we moved in two weeks ago.  He is a inconsiderate, rude, condescending douchebag slob.  So when he came home tonight drunk and woke me by throwing up in the bathroom sink, I decided enough was enough.  After he passed out, I took some photos.  

In the morning, he found a series of these photos printed out with instructions on what he needs to do to correct his behavior.  Each time he fails to follow the instructions, one of his friends is sent a photo and an invitation from Bill asking to be used like a whore.  

In the two weeks since the night the photos were taken, his behavior has greatly improved, he has learned some new skills and eight of his former friends have made use of him.
