Groove Tube [Blu-ray]

This mixed bag of comedy sketches has a grand time skewering TV commercials, children's shows, the nightly news, sitcoms and pretty much anything related to the boob tube. One of the best skits features Ken Shapiro as kids-TV host "Koko the Clown," a somber personality who likes to smoke pot and read titilating segments of Henry Miller's Tropic of Cancer. Chevy Chase, Richard Belzer.
