The Tonight Show host Jimmy Fallon was the first to introduce the infectiously fun music game Lip Sync Battle. The game is quite simple. Two players take turns lip syncing with a pop song as entertainingly as possible. Who ever gets the most cheers wins. 

Now, the game is being picked up as a TV show on Spike. This trailer for the first episode, featuring Anna Kendrick, Jimmy Fallon, The Rock, and more, has instantly gone viral!
