Biz Markie appeared on 'Jimmy Kimmel Live!' on Thursday (Nov. 17), to celebrate the late night TV host's second annual National Unfriend Day with an updated version of the Juice Crew legend's 1989 classic 'Just a Friend.'

"National Unfriend Day obviously is sweeping the land. It's become a major holiday, it's even better than Arbor Day, I think," Kimmel joked, introducing Biz.

Following some lame Facebook friends-themed snaps by Drew Carey, Paul Scheer and Kaley Cuoco, Biz went into 'Just Unfriend,' a humorous 2011 spin on friend-zone exile, bringing back his signature Mozart cape and wig from the original video.

"Let me tell ya story, what happened to me/ It all started when I friended her on FB," Biz rapped, before interpolating his popular chorus. "Oh baby you, don't got what I need/ So I say we just unfriend/ So I say we just unfriend."

Nobody beats the Biz.
