Jimmy Fallon played host to another epic battle on The Tonight Show yesterday.
Following the first-ever nip-sync duet with Terry Crews, which came on the heels of an iconic Emma Stone lip-sync victory, Will Ferrell and Red Hot Chili Peppers drummer Chad Smith appeared on the program Thursday.
The stars wore matching leather jackets, sneakers, Kiss shirts and backward baseball caps while taunting each other with verbal jabs before taking their fight to the musical stage... Drum-Off style!
Who came out on top? Watch the hilarity and decide for yourself:
Ferrell or Smith? Smith or Ferrell?!?
