Watch Brian Williams Rap 'Good Vibrations'

You know you want to.

This just in from the "Killing It" department: Late Night With Jimmy Fallon has done it again. Just minutes after that monologue joke that-- yep, just thinking about it still makes me laugh -- the show came back strong last night with a special honour for guest Mark Wahlberg. Have you ever wondered what it might sound like if Brian Williams covered "Good Vibrations" by Marky Mark And The Funky Bunch? Wonder no more.
