Mary-Kate and Ashley Olsen were good friends with this star while they were on the set of Full House. Remember Derrick? He was Michelle’s classmate and buddy. Well, his real name is Blake McIver, and he’s now a go-go dancer. The 28-year-old also took the role of Waldo in 1994’s The Little Rascals. If you watched the show and can’t recall who it was? See his go-go dancing outfit (shirtless) in the gallery below!
