Jimmy Fallon hosted his second Lip Sync-Off on Late Night last night (the first, you may recall, was performed — and some might say owned — by John Krasinski), this one featuring The Office co-creator/tall drink of water Stephen Merchant and human ukulele/your imaginary boyfriend Joseph Gordon Levitt.

Jimmy stuck to '80s, lip syncing "Don't You Want Me" by The Human League and "Take On Me" by A-ha, while both Merchant and JGL began with classics before veering into contemporary hits. I'd tell you what they sang, but I don't want to ruin the surprise. I will spoil this, though — both of them came ready to dance.
