John Krasinski was on Late Night With Jimmy Fallon on Tuesday to help promote the forthcoming, star-studded series finale of NBC's The Office. As he's wont to do, Fallon incorporated a musical aspect thanks to Krasinski's idea for a lip sync-off.
Each guy got to choose three songs as they alternated performances. Fallon goes with "Don't Cry Out Loud" by Melissa Manchester, "They Want Efx" by Das EFX, and "Somewhere Over the Rainbow" as performed by Sam Harris on Star Search in 1984.
Krasinski goes with "Teenage Dream" by Katy Perry, "Peter Piper" by Run DMC, and "I'll Make Love to You" by the infamous Boyz II Men. After Krasinski ditches his jacket and loosens his tie, Fallon joins him to finish off the performance.
