NBC's parent company Comcast has put the kibosh on an episode of the U.S. network's show "Fear Factor" showing contestants drinking donkey urine and semen.

NBC said Monday's installment of the reality competition series will be a repeat of an earlier episode, but TMZ said "Hee Haw! Hee Haw!" -- a new episode featuring contestants chugging donkey semen, then chasing it with glasses of urine -- was initially slated to air.

"Fear Factor" host Joe Rogan joked about the challenge, which was taped last summer, in a recent interview with the New York Daily News.

"I say, in the real world, in a healthy society, you're not supposed to eat animal [expletive,] but guess what? Here you have to eat animal [expletive] if you want to win $50,000," Rogan said.
