The plotline for the premiere episode of 'The Minor Accomplishments Of Jackie Woodman' on IFC hinged on bumping into (literally) Sally Kellerman. As a follower of the Step-Up cult, Ms. Kellerman was spacey, self-centered, and by the end, scarily evil.
It was probably the most destructive depiction of one's self in a sitcom since Lloyd Bridges portrayed himself on 'Ned & Stacey' as a kleptomaniac neo-Nazi cross-dresser.
Also appearing as themselves in the episode were Merrill Markoe and 'Simpsons' producer Sam Simon. And both of them were the epitome of Hollywood's two-faced denizens.
