Ryan Reynolds: I bet my butt and lost ... and won

Ryan Reynolds may never be more grateful for losing a bet.

Reynolds and Rob McElhenney, who document their experiences as co-chairman of the Welsh football club Wrexham A.F.C. on the FX series “Welcome to Wrexham,” made a bet that Reynolds would broadcast his colonoscopy if McElhenney could learn Welsh. Sure enough, McElhenney learned Welsh and Reynolds proved to be a man of his word. …

After the procedure, Dr. Lapook let Reynolds in on what happened, noting he found “an extremely subtle polyp.”

“This was potentially life-saving for you,” he continued. “I’m not kidding. I’m not being overly-dramatic. This is exactly why you do this.”
