'My Big Fat Obnoxious Fiance'
Would you trick your family into thinking your were marrying a heinous jerk if it meant $250,000 for you and $250,000 for them at the end of the prank? One woman did just that in 2003, but there was a catch -- she didn't know that the big, fat, obnoxious fiance was an actor. She made it to the end after some painfully awkward reality TV moments, broke down in tears when the joke was revealed to be on her, and ended up taking home double the amount of money for herself and her family.
