Watch Jimmy Fallon Challenge Joseph Gordan Levitt in Epic Lip Sync Battle [VIDEO]

This is the most epic lip sync battle ever and it all happened on Late Night with Jimmy Fallon!

I won't even try to pretend like this did not make me LOL. I nearly fell out of my chair a couple of times while I watched this. All I kept thinking to myself is that Rob, Chandelle, and I have got to do this! We must have a lip sync battle here at KISS-FM! I will work on trying to get them on board for such shenanigans. In the meantime, watch Jimmy Fallon, Stephen Merchant, and Joseph Gordan Levitt lip sync to great songs that you love!
