Jimmy Fallon says this lip sync-off was actually John Krasinski’s idea, but it definitely seems like something Fallon would have come up with. Krasinski was visiting Late Night with Jimmy Fallon to talk about the end of The Office, but this battle wound up being the high point of the interview.

Seriously, watching Krasinski lip-syncing to Katy Perry’s “Teenage Dream” is worth an investment of eight minutes of your time. And when Krasinski gets all sexy with Boyz II Men’s “I’ll Make Love to You”…well, see for yourself.
