The middle, “disgusting food or drink” segment on this Mondays ‘Fear Factor’ will have the contestants drinking glasses of donkey semen, and NBC is so upset they threatened to stop the show.

Well, actually the show was filmed over the summer. It’s not like it’s live. Getting that much donkey semen on a live show would be tough on the farmers wrists. So really all NBC threatened to do was make people drink donkey semen for no reason.

We’re told the challenge involved teams of twins drinking the full glass of donkey semen — with a glass of urine thrown in for good measure. Contestants had to drain both glasses in order to move on to the next round.

Our sources say NBC execs had multiple pow-wows … but eventually gave the thumbs up.

On a somewhat related note, Perez Hilton now says he really really really wants to be on ‘Fear Factor’. “This way it will all be nice and legal,” he said, though I’m not sure what “it” refers to.

(“You know who isn’t upset about all this? The donkey who got jacked off until he filled three pitchers,” said the Army Donkey with a bullet-magnet slowly riding him through an open field. “Fuck my life,” he continued.)
