Now that The Office has wrapped, John Krasinski has the freedom to do awesome things like grow a beard and participate in epic lip sync battles with Jimmy Fallon. Apparently, Krasinski had suggested it, too, so thank you. Fallon opened with Melissa Manchester’s “Don’t Cry Out Loud,†which John upped with Katy Perry’s “Teenage Dream.†Then followed Fallon’s Das EFX’s “They Want EFX†matched against John’s cover of “Peter Piper picked a peck of pickled peppers,â€Â and for the ultimate showdown, Jimmy on “Over the Rainbow,†and John down on bended knee with Boyz II Men’s “I’ll Make Love to You.†Catch all the jacket-stripping, ear piece-grabbing, in-your-face-swaggering affectations of the lip sync battle straight ahead.
