Bill Belichick and the New England Patriots pride themselves on keeping their lips sealed when it comes to injuries and incidents regarding their players. So Belichick must've been over the moon when he saw his tight end Rob Gronkowski—who is recovering from ACL surgery—make a guest appearance on "Whose Line Is It Anyway?" last night. As you can see in the video above, Gronk showed off those famous dance moves of his, while Wayne Brady provided the vocals.

And just in case dancing wasn't enough, the Gronk came back later in the show to make a few boob jokes and lift some weights. Cheer up, Bill, at least the knee looks healthy!
