Micucci appeared in five episodes of Scrubs ("My Lawyer's in Love", "My Absence", "My Chief Concern", "Our Histories", and "My Finale") as Stephanie Gooch, a ukulele player with whom Ted Buckland begins a relationship. She performs her song "Mr. Moon" and an adapted version of "Fuck You" (retitled "Screw You" for ABC), a song she typically performs as part of the musical duo Garfunkel and Oates. In 2009, she starred in the short film Imaginary Larry, co-written and co-directed by Riki Lindhome, her partner in Garfunkel and Oates.

From 2009 to October 2011, she performed "Playin' with Micucci" on the third Monday of the month at The Steve Allen Theater in Hollywood, California.
