Biz Markie threw out the first pitch in Oakland so the MLB Tonight guys sang 'Just a Friend'

While younger folks might know him as the beatboxing alien from Men in Black II, most of the population is familiar with Biz Markie for his 1989 Top 10 single (and the greatest karaoke song of all time) "Just a Friend":

On Wednesday, the Athletics hosted Mr. Markie at O.co Coliseum where he rocked some hat tilt and threw out the first pitch.

He also made some root beer floats, led the crowd in singing "Take Me Out to the Ball Game" and hung out with Jeff Samardzija.

And later, the MLB Tonight guys used the appearance as an excuse to crank out a few bars of the iconic hip-hop classic.
