What kind of sorcery does Bill McClintock do with his mashups? I honestly thought the pinnacle was when he did a mashup of "Round and Round" by Ratt and "I Heard It Through The Grapevine" by Marvin Gaye. Then, Bill took it to the next level with "Sulfur" by Slipknot and "Wannabe" by The Spice Girls. Just when you think there is NO WAY ON GOD'S GREEN EARTH that Bill McClintock outdoes himself, he raises the bar even further with a mashup of "Sweating Bullets" by Megadeth and "Rockin' Robin" by The Jackson 5. Check it out above! It will not leave your head ever again! This man is a total genius!
