In "Robot Chicken," no pop culture target is safe. Old-school stop-motion animation and fast-paced satire are the hallmarks of this eclectic show created by Seth Green and Matt Senreich. Action figures find new life as players in frenetic sketch-comedy vignettes that skewer TV, movies, music, and celebrities from Quentin Tarantino’s blood-spattered epics to "The Real World," in which a cast of superheroes takes the place of drunken 20-somethings.
