While 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.
