One of the most memorable episodes of The Venture Bros. was the one with this twisted take on the gang from Scooby Doo (above).
From L-R, that's Valerie Solanas (author of the Scum Manifesto, and the woman who shot Andy Warhol), Patty Hearst, and (serial killer) Ted Bundy. Not shown - "Son of Sam" killer David Berkowitz (the "Shaggy" character) and his sinister talking dog.
Venture Bros. returns for its fourth season on Cartoon Network on October 18.
