A buddy of mine at work was telling me about an episode of the Dirty Jobs TV show. The guy was doing a really grossing job and was about to throw up and someone told him to smile. Oddly, smiling will keep a person from throwing up. Well, it didn't quite work. But the fellow started dancing around. That kept him from getting sick. LOL!
I thought the bit about smiling was interesting and the dancing around too funny. Plus I wanted to share.
