Instead of Jon sitting at his desk during the opening of the Daily Show (via Huffington Post), Justin was in his place wearing a suit and kicking off the show.

Only... it wasn't really Justin!

Jon and Justin had a Freaky Friday moment and switched bodies, but Justin wanted to switch back a little more than Jon.

Still, Jon got to keep a souvenir from the Biebs!
