There's this British show called Naked Attraction whose premise is the contestant has like 6 potential matches based on their surveyed preferences and the game is you get these people nude in front of you but they are revealed to you from the feet up and you have to eliminate people based purely on physical characteristics.

After they're down the last two candidates and there has been face and voice reveal the contestant also gets nude and they stand there staring at each other's junk and the contestant picks one to go on a date with. Hopefully the person they chose is also interested...

Well even after they're standing there absolutely horny for each other they go on a date and most of the time they realize they don't like each other at all. Simply amazing.
