'Who's Your Daddy?'
The premise: A grown woman who was adopted as a baby is introduced to 25 older men, one of whom is her biological father. If she can correctly guess which one is her "daddy," she wins $100,000. Not revolting enough? If she picks the wrong match, the incorrect paternity candidate wins $100,000 instead. The show was canceled after ample criticism from adoption rights groups and the general public.
