Does Jimmy Fallon really think he has a chance at beating Liam Neeson in a round of arm wrestling? The Tonight Show host was so confident he could beat the Taken 3 star that he even played a little game of "If I Win" during the match.
"If I win, I'm going to get a tattoo on my lower back that says: 'Better ingredients, better pizza, Papa John's.'"

Neeson, 62, also got in on this, adding, "After I win, I'm gonna find 100 Jimmy Fallon lookalikes, put them in a room together and throw you the world's creepiest surprise party."
