John McEnroe Reveals the Most Well-Endowed Tennis Great He Ever Saw in the Locker Room: WATCH

Seven-time Grand Slam winner John McEnroe sat down with Andy Cohen on Watch What Happens Live! where he was asked a series of probing questions in a game of ‘Plead the Fifth’.

After refusing to give up the name of a famous older woman he once dated and saying how he’d do if he had to face Serena Williams in a match, McEnroe gamely revealed the most hung tennis great he’d ever faced in the locker room.

McEnroe said knowing about his opponent’s massive member fueled their rivalry: “It pains me to say this, because he was one of my most hated rivals. And I’m giving him a lot of credit right now.”
