Mike Tyson used a prosthetic penis to test drugs, holding his baby’s urine to cover up cocaine marijuana use.

Mike Tyson may not have had the best reputation in the boxing ring for biting someone in the ear, but he is an undisputed legend both in the ring and in the world of pop culture.

The boxing champion has been celebrated for years, and while he was fighting for the title, he was living the life of a rock star at the same time.

In his podcast Hotboxin ‘With Mike Tyson, the boxer regularly details what his award was like, and this week he revealed how he was doing his drug tests.

To prevent cheating in sports, athletes are regularly drug tested using urine samples to look for evidence of PED usage, or any other banned substances.

Before the testing process got more invasive, Mike Tyson went around the method by using the “whizzinator”, a prosthetic penis that stores urine inside, specifically designed to get by drug tests.

“It was awesome, man,” said Tyson during a conversation with Jeff Novitzky, UFC’s Vice President of Athlete Health and Performance.

“I put my baby’s urine in it. One day, I used my wife’s and my wife said, ‘baby, you better hope that it doesn’t come back pregnant or something’. So I said, ‘no, we ain’t gonna use you no more. We gonna use the kids.’ ‘Cause I got scared that the piss might come back pregnant.”

Tyson says that, while he avoided performance-enhancing drugs, he often partook in cocaine and marijuana consumption, which explains why he would need a fake penis to take drug tests.
