Showalter has also had several smaller roles in movies and TV shows. He played Ron Parker, the arrogant host of "Cheap Seats", on ESPN Classic in the pilot episode. However, after a bookcase fell on Showalter's character, tape librarians (and brothers) Randy and Jason Sklar took over the hosting duties. Showalter spent a brief time as a correspondent on "The Daily Show" (1996). He is also one half of The Doilies, an acoustic comedy band, in which he sings lead vocals opposite guitarist Zak Orth. In 2005 he wrote, directed and starred in the film "The Baxter".
