So don't watch it
I love watching bad TV, I don't give a shit if it's rigged, it's funny and a guilty pleasure.
That said Fear Factor isn't one of the shows I watch. I think that show is retarded.
You're getting paid about $25,000 (after taxes) to eat foul shit and do disgusting 'dares'. But for what? That's not enough money for me to humiliate myself and barf on TV. I could get a part time job and make that in a year.
And while we're on the subject, how is eating worms a 'fear'? I'm not afraid to eat bugs, I just think it's gross and I don't want to do it. They should call that show 'stupidity factor' or 'look how gross I am'.
