I agree with the age limits, in the case of big brother they should have stopped making them after 1 or 2 years. They should not have kept making these, they are turning into freak shows where they gather extreme personalities, gays and ex-porn stars. Bringing someone in with tourettes was a bit out of order as the producers of this show obviously pulled him in as they thought he would be funny to watch, which he is, but the producers undoubtably chose him in a kind of bullying make fun of him mentality.
I might go for big brother next year, thinking that if i say i'm an ex-crack addict who has slept with 200 girls and suffers from paranoid schizoprenia I will be thrown straight into the show.
