Things got physical when Ryan Reynolds [1] dropped by The Tonight Show on Monday. During Ryan's appearance, he and Jimmy Fallon [2] played a friendly game of Slapjack, which entailed a high-stakes game of blackjack where the loser of each round got smacked in the face with a giant rubber hand. At one point, Ryan gets nailed in the head pretty hard, and just in case you miss it, the slap gets replayed in slow motion. Watch the funny clip above, and then relive the times he played "Water War" [3] and "Egg Russian Roulette" with Jimmy [4].
