Jumping on the #hashtageverysentenceasmuchasyoucan bandwagon, the duo show us really how silly everyone is for really doing it. #PleaseStopEveryone might as well be the message for this week’s “Timberlake Tuesday.” Best part? Obviously the ending!

And yesterday, Jimmy brought back our favorite celebrity competition on his show – lip sync battle. Now, if you remember his last memorable one with The Office’s John Krasinski, you understand why we were so stoked to see he was going against Joseph Gordon-Levitt and Stephen Merchant.

JGL is pretty much a natural at the game, taking on Elton John’s “Tiny Dancer” and Nicki Minaj’s “Super Bass,” as he jumps all around the stage, nailing every word. But it was Stephen that totally stole the show! I mean, his rendition of Beyonce Z’s (LOL) “Single Ladies” is pretty much on point – especially with the signature dance brought in. Bravo, fellas. Bravo.

JT’s or JGL’s?
