In addition, he also starred as many original characters, including Nick Burns, an IT Support nerd, Pat "Sully" Sullivan, one of the Boston Teens with Rachel Dratch, and in Jarret's Room, a fictional webcast hosted by stoner college students Jarret (Fallon) and Gobi (Horatio Sanz).
Sanz has described Fallon and himself as "super-functioning alcoholics," and stated, "They say that kind of goes hand in hand with SNL, some kind of substance-abuse issues, because it's so stressful you easily find yourself blowing off steam a lot." Fallon initially envisioned he would spend three years at SNL, like Belushi, but he was persuaded to stay on for an additional three when given the reins to Weekend Update (which he would co-host with writer Tina Fey).
In his later years on SNL, Fallon co-starred in skit titled The Barry Gibb Talk Show alongside musician Justin Timberlake, where the duo portrayed Bee Gees brothers Barry and Robin Gibb.
In May 2009, 14 years after he left college a semester early to pursue a comedy career, he returned to receive his Bachelor of Arts in communications.
He was a double headliner that day at the Saratoga Performing Arts Center, earning an honorary degree reflecting his achievements and then joining classmates to collect his degree. Rose awarded Fallon his diploma after he earned experiential learning credits through a portfolio review of his television work.
Fallon possessed a strong female fan-base, receiving numerous letters from fans and becoming the subject of numerous fan-sites.
