Character: Gail von Kleinenstein, emotionally needy divorcée and art teacher
Pre-WHAS: Like Garofalo and Poehler, Shannon is an Saturday Night Live alum, who actually joined the show when the Reality Bites star quit in the middle of the tumultuous 1994-95 season. At SNL, Shannon was best known for playing the deeply strange Catholic school girl Mary Katherine Gallagher, later featured in the 1999 movie Superstar.
Post-WHAS: Around the same time that she shipped off to Camp Firewood, Shannon left SNL, and in the years since she’s been a go-to guest star and supporting player for movies and TV. Her best work since 2001 has been in the short-lived sitcom Kath & Kim and in the HBO series Enlightened (for which she scored an Emmy nomination).
