A comic legend was born when a tall ginger took over for David Letterman and premiered a show called Late Night With Conan O'Brien in 1993, but before he cracked jokes for a living, O'Brien hit the books as a history and literature major at Harvard. He sharpened his communication skills writing for the Harvard Lampoon and graduated magna cum laude from the Ivy League school in 1985. 

Diploma in hand, Coco wasn't quite sure what his future would look like. "I didn't know what I was going to do, I didn't know how I was going to do it," he told USC's second annual Comedy @SCA Festival. "But I remember thinking it's not going to be medical school, it's not going to be law school, the male modeling is not going to happen, and it's going to be, definitely, me being in show business."
