It may not be the weirdest thing Lamar Odom has ever done, but in 2004, the NBA champ wore a prosthetic penis to pass a drug test for the upcoming Olympics in Athens.

Odom, 39, makes the revelation in his new memoir, “Darkness to Light,” according to People magazine.

“There was no way I was going to pass,” the former husband of Khloe Kardashian writes of the requisite drug test.

“I had been smoking weed every day that summer. Panic set in.”

Some online research on how to beat a drug test led him to order “a giant, rubber, black c— to arrive the next day,” he wrote.
