Dirty Jobs – Mike Rowe’s quest for filth led him to a business called “Hair Fairies” this week. It was off to a good start when Mike spent several minutes trying to figure out the extremely busy promotional art on their awning, before finally revealing that they treat people for head lice. Which is pretty gross, but nowhere up to Mike’s usual level. The real treat came when producer Dave Barsky accidentally put his hand on a lice-covered towel and then scratched his head. For safety’s sake, they had to shave his head. For humor’s sake, they shaved it on camera and let amateurs help.
