Probst admitted that he sometimes did this because he did not want to be a cause of delay for the show's taping. This is another addition to his long list of misadventures during tapings of previous seasons. It can be remembered that he got electrocuted because he urinated in an electric fence. He also got stung by a jellyfish near his genitals and also had a close encounter with a reticulated python.
Note to Jeff Probst: In addition to electric fences, jellyfish, and reticulated pythons, some other good things to keep your penis away from: the Jaws of Life, crocodiles, barbed wire, guillotines, electric eels, oscillating fans, and Ted Haggard.
