John Krasinski, we’ve loved you ever since we heard that first witty line come out of your mouth on the premiere of The Office. Fast forward nine seasons later and we’re still completely head over heels for you and your lip synching battle on Late Night With Jimmy Fallon has taken it to a whole other level. Seriously, Emily Blunt, you are the luckiest lady in the world.

Okay, enough of our JK appreciation moment, let’s move on to this hilarious clip. The Office is coming to an end on May 16th so John has been making the talk show rounds, reflecting back on the past nine seasons. Stopping by Jimmy Fallon's show, he did all that and showed off his impressive lip synching skills, completely owning Jimmy.

Kicking off the competition with Katy Perry’s “Teenage Dream,” John shined with songs like Run DMC’s “Peter Piper” and, his best one, Boyz II Men’s “I’ll Make Love To You.” Let’s just say this guy doesn’t joke around when it comes to lip synching -– he takes it very, very seriously –- and we totally appreciate it.

John, we’ll say this again –- we love you. Forever and always.

What song was your favorite from John and Jimmy’s lip synching contest?

And did John totally dominate it?
