What he's up to now: The principal of Bayside High is now 63. Since SBTB, ummmm...I'll just quote from his Wikipedia page: "On August 31, 2009, Haskins released his first music album called Karaoke With Your Favorite Principal Dennis. On the album, he sings everything from 'Piano Man' to 'Mustang Sally,' the latter being a duet with Hulk Hogan's daughter Brooke Hogan."
