Jimmy Fallon hosted a battle for the ages on Tuesday night. And most would say he lost, including Fallon himself. The challenger: John Krasinski from "The Office." The game? Hardcore lip-sync contest.
Well, maybe not "hardcore" considering the first two songs performed were "Don't Cry Out Loud" by Melissa Manchester and "Teenage Dream" by Katy Perry. But as it turns out, Krasinski may actually be better on stage with a fake microphone than he is at pushing paper in a cubicle.

The second round of the battle, the two took on old-school hip-hop.
