LeBron James, Jimmy Fallon play 'Faceketball'

LeBron James presumably got more of a workout than he expected when he appeared on The Tonight Show on Tuesday, but it was all in good fun.

Host Jimmy Fallon surprised the Cleveland Cavaliers star by challenging him to a game of "Faceketball," which may or may not be a sport that brings back memories of childhood.

James warmed up to the idea as Fallon was explaining the rules and he deserves some marks for giving an honest effort.
