NBC and "Fear Factor" have decided NOT to air the disgusting donkey semen episode tonight.

As we heard last week, the episode included a challenge where the teams had to drink full glasses of Donkey Fluids. There was one glass of donkey pee, and one glass of donkey semen.

Initially, they were going to air it, but it seems they've changed their minds.

NBC has stopped running promos for it, and the episode, "Hee Haw! Hee Haw!", has been removed from their schedule.  Instead, tonight's "Fear Factor" is a repeat of an episode that aired four weeks ago.

This would please something called the American Donkey and Mule Society.

They released a statement saying,

[We don't] condone use of the animals in such a manner . . . we feel this is a negative event, and was not well thought-out by the producers."

By the way, the episode was also supposed to feature twins girls in bikinis being shocked by an electrified fence.  If the donkey stuff HAS been dumped, it's unclear what will happen to this footage.
