Mike Tyson went to great lengths to avoid failing drug tests during his career.

On the latest episode of the "Hotboxin' with Mike Tyson" podcast featuring UFC vice president of athlete health and performance Jeff Novitzky, Tyson revealed he would put his ex-wife and child's urine in a Whizzinator - a prosthetic penis - when being tested.

"It was awesome, man ... I put my baby's urine in it," Tyson said. "And sometimes, one time I used my wife's. My wife said, 'Baby, you better not hope that it comes back pregnant or something.' And I said, nah, so we ain't gonna use you any more, we're gonna use the kid. I got scared that the piss might come back pregnant."

The former heavyweight boxing champion previously spoke about the Whizzinator in his 2013 book "The Undisputed Truth," explaining how he used the device after using cocaine and marijuana prior to a 2000 bout against Lou Savarese. He was fined $200,000 later that year after testing positive for marijuana following a fight against Andrew Golota.
