7. Biz Markie
One of the MCs responsible for bringing rap to the mainstream, Harlem's Biz Markie made hip hop history when "Just a Friend,” his off-key anthem to unrequited love, became a top ten hit. Even though the Biz's other tracks like "Pickin' Boogers” and "Toilet Stool Rap” wouldn't find the same success, he's had some memorable career moments, including paying tribute to Elton John on The Chris Rock Show and showing off his ample belly on VH1's Celebrity Fit Club. What else would you expect from an MC known as the Clown Prince of Hip Hop?
