Charlie and Jake's first encounter with a woman in the supermarket is with Suzanne, played by Jennifer Taylor in her first appearance as one of four characters: Suzanne here; Tina in Last Chance to See Those Tattoos (2004); Nina in Our Leather Gear Is in the Guest Room (2007); and finally, recurring character Chelsea for around 30 episodes.
Despite being a main character throughout the show's run, Charlie's (and later, Walden's) housekeeper, Berta, didn't make her first appearance until the fourth episode of season 1.
Episode title ("Most Chicks Won't Eat Veal") spoken by Charlie to Alan, in the original unaired pilot.
