Saw this elsewhere and thought it was a good idea...
A reality show idea with gay men.
11 gay men and 1 straight man are locked in a house.
The object is for the gay men to find out who isn't gay.
Once a week someone gets voted out, until 2 are left, or until the straight man is out.
If the gays manage to outvote him, they win 1 million dollars.
If the straight man is among the 2 last people in the house in the end, he wins 1 million dollars.
Now here's the twist: None of the men are actually gay.
All of them think that they are the one straight man.
