As he explains in an interview with GQ, Tatum said that Hill bet him that "21" wouldn't make more than $35 million in its first few days of release -- and if it did, Hill said he would kiss Tatum's penis. Cut to that film's opening weekend in May 2012, and "21" raked in $36.3 million.
"I haven't made him do it yet. For obvious reasons," Tatum told GQ about winning the now-regrettable bet. "That's a bad bet to lose -- it's not too good to win, either. But definitely the shame of it would be enjoyable. It's my trump card, for sure. He tries not to bring it up at all costs. Unless he did something horrible to me, I don't know if I could ever cash it in. It would change our relationship forever."
Tatum also said that if he ever did decide to make Hill pay up, he'd have to clear it with his wife, Jenna Dewan-Tatum, first.
As for what led Hill to suggest such terms in the first place, the actor didn't have much of a comment for GQ.
"Channing and I say a lot of stupid stuff when we drink together," he told the magazine.
"22 Jump Street" opens on June 13.
