Is this the most vile reality show stunt yet? US Fear Factor contestants served glasses of donkey semen (with a urine chaser)



A US television is set to win the prize for the vilest game show stunt yet.



Fear Factor has filmed a segment in which contestants of the NBC show are challenged with drink a mug of 'donkey semen' - with a chaser of urine for good measure.



The stomach churning segment was apparently filmed last summer and is expected to air next week.

Show executives had had their reservations and there was plenty of controversy behind the scenes.



Host Joe Rogan hinted about the stunt in an interview with America's Entertainment Weekly some weeks ago.



'The one I want to give you, I can’t,' Rogan said, when asked what was the grossest challenge that was shot for this season.

'They’re not even sure if they’re going to air it. It’s so over the top and ridiculous. When they told me, I really though they were joking at first. I don’t know where the debate is, but NBC is not sure if they’re going to air it.'



The challenge required teams of twins to drink a full glass of donkey semen - with a glass of urine thrown in for good measure.

Contestants had to drain both glasses in order to qualify for the next round.



And the episode, which will be aired on Monday, will reportedly see several contestants completing the questionable challenge.

It is unclear whether the ingestion of such liquids pose any health risk to the contestants.

The American sports stunt/reality game show is produced by Endemol USA, and sees hopefuls compete for a grand prize of $50,000.



The original Dutch version was called Now or Neverland.



The stunt is similar in nature to those on British reality show I'm A Celebrity... Get Me Out Of Here!.

On the ITV programme, contestants have to eat a variety of disgusting animal parts such as testicles and eyeballs in a bid to win meals for the rest of the camp.
