There's a sidebar article titled "9 Terrible Ideas" about the most outlandish pitches TV execs have received for new shows. I'd link to it, but I can only find the sidebar in the print version--not online. (I'm not making this up.)
Here are some:
Six real-life pimps together in a house. No challenges, no voting. They just live in the house and they pimp.
Real prisoners try to escape from a real prison. The winner's victim(s) get the prize money.
A contest to find America's best stripper. It's American Idol with lap dances.
Who Wants to Donate Their Sperm?
Like The Bachelorette, except the woman doesn't want the guy--just his DNA.
