Jimmy Fallon and John Krasinski face off in lip-syncing battle

With “The Office” set to retire May 16 after nine seasons on NBC, series star John Krasinski has been hitting the talk-show circuit.

On Tuesday, he stopped by “Late Night,” where he recalled the terror he felt his very first day on the show, talked about attending the Met Gala on Monday and, most notably, engaged in an epic lip-syncing battle with host Jimmy Fallon.

The two went head-to-head, hamming it up to a series of hits by Katy Perry, Run DMC, Das EFX and Boys II Men. They started out relatively tame, gradually working up to James Brown levels of exertion.

Ultimately, Fallon probably edged out his guest by a hair, but hey, he does this every night. What do you expect?
