MC Hammer is arguably the most famous batboy in the history of baseball. The Oakland native and hip hop artist served in the A's clubhouse during the Swingin' A's dynasty years in the '70s.
Hammer returned to the O.co Coliseum on Thursday to throw out the first pitch before Game 5 of the ALDS against the Tigers. He even got in a little dance move before shaking hands with pitcher Evan Scribner. Sadly, he wasn't wearing parachute pants.
The "U Can't Touch This" singer also hung out with Coco Crisp.
