15. Dr. Faye Miller
Showcase Episode: "The Beautiful Girls"
Yet another inspired Sopranos casting touch — Carla Buono was Christopher's wife Kelli before playing Dr. Faye Miller, the steamy psychiatrist who analyzes the fuck out of Don. She totally has his number: "You only like the beginnings of things." And oh yeah, she has a dad in the mob — "He's a handsome two-bit gangster like you."
