You learn something new every day! Mike Tyson may not have needed much help boxing in the ring in his day, but passing a drug test is a different story! The former Heavyweight Champion of the World gave Chelsea Handler a step-by-step procedure on how to use a fake penis during a drug test while appearing on Chelsea Lately this week.

"It works really effectively. It just doesn't work the way you think it works, but it works if you wanna pass a drug test," he said to Handler during an appearance on her E! talk show on Monday, Dec. 2. "You take it out -- it has somebody else's urine in it, of course -- you hope it's not a woman's urine and they take a pregnancy test," the 47-year-old athlete joked. 

He then went on to discuss how the drug tester usually looks away once you begin the test anyway. "You just make noise, and normally if you're a guy and you pull it out in front of them [the drug tester], they're like, 'Whoa, whoa," he said. "And then you do it."

Tyson explained that he employed the trick before big bouts during his heyday. Though Handler seemed shocked he got away with it, he made it seem simple to hide. "It's connected to a jock strap," he said.

As for what color the fake penis was? He quipped: "I don't know. Tan, brown, cream-colored!"
