In 1944, Pitts tackled Broadway, making her debut in the mystery, Ramshackle Inn. The play, written expressly for her, did well, and she took the show on the road in later years. Post-war films continued to give Pitts the chance to play comic snoops and flighty relatives in such fare as Life with Father (1947), but in the 1950s she started focusing on television. This culminated in her best known series role, playing second Banana to Gale Storm on CBS's The Gale Storm Show (1956) (also known as Oh, Susannah) in the role of Elvira Nugent ("Nugie"), the shipboard beautician. In 1961, Pitts was cast opposite Earle Hodgins in the episode "Lonesome's Gal" on the ABC sitcom, Guestward, Ho!, set on a dude ranch in New Mexico. In 1962, Pitts appeared in an episode of CBS's Perry Mason, "The Case of the Absent Artist". Her final role was as Gertie, the switchboard operator in the Stanley Kramer comedy epic It's a Mad, Mad, Mad, Mad World (1963).
