Jimmy Kimmel's 2nd annual 'National Unfriend Day' was a success. We've already shown you how the Peanuts gang wants you to dump some friends on Facebook, now it's Biz Markie's turn.

But he's not the only celebrity that gets involved.

Biz Markie, whose 'Just a Friend' song is the inspiration for Kimmel's parody, is  joined by 'Price is Right' host Drew Carey, comedian Paul Scheer and 'Big Bang Theory' star Kaley Cuoco. Check out the clip below and then dump some of your Facebook friends so that you can like us on Facebook.
