I cant actually believe this could either be made, or allowed to be made... but its reported:
"FOX is turning a grown adopted child's search for her father into a reality/game show called "Who's Your Daddy."
On the Jan. 3, 90-minute special, the woman will face eight men — one is her father, and the fakes' goal is to trick her into thinking they are.
If, after three elimination rounds, she picks out her real father, she wins $100,000. If she picks the wrong one, the fake daddy gets the big-bucks prize. — Post TV Staff"
