Thomas Lennon

While Lennon was a member of The New Group, the comedy troupe changed its name to The State. As they performed their material at theaters and clubs in New York City, they worked on the MTV show You Wrote It, You Watch It. This led to the self-titled series The State (1993–95), which was nominated for a 1995 Cable Ace Award for Best Comedy Series. That same year, they created a special for CBS called The State's 43rd Annual All-Star Halloween Special.

Following the departure of The State from MTV, and failed long-term deals with both ABC and CBS, Lennon, along with Kenney, Robert Ben Garant and Michael Ian Black, went on to create and star in the Comedy Central program Viva Variety (1997–99). The show was based on a sketch that Lennon had written for the final season of The State, called "The Mr. and Former Mrs. Laupin Variety Programme." Viva Variety received a 1997 Cable Ace Award nomination for Best Comedy Series. After Viva Variety, Lennon, Kenney and Garant created and starred in Reno 911! (2003–09). The series was initially slated for Fox, but the channel rejected it for being too risque, and the program eventually ended up on Comedy Central.

Lennon has appeared as a guest star in dozens of TV shows, including The League, Childrens Hospital, Party Down, New Girl, How I Met Your Mother, Comedy Bang Bang, Don't Trust the B---- in Apartment 23.
