I had a Social Studies teacher that used to tape wedding announcements from the newspaper to the blackboard. He would tape all the pictures of the ugly people who he felt shouldn't reproduce.

It was funny in a mean way. He'd been a teacher, a very good teacher for 20 plus years. The photos came from the local paper. I once asked him if he was worried that the picture might be a sibling of one of his students thus offending them. "No' he said, "if anyone knows how ugly they are it would be their siblings"
