Two grown men playing a game called Sticky Balls? It must be a game on The Tonight Show with Jimmy Fallon. WWE Superstar John Cena was on Tuesday's Tonight Show promoting his new reality show American Grit and stepped into the Sticky Balls arena to battle with Jimmy Fallon. The object is to throw velcro balls at your opponent. After 45 seconds, whoever has more balls stuck to them is the loser.

We've got all kinds of jokes going through our heads too. Find out who had more balls on their suit and see more of the best of Tuesday's late night TV below.
