If for no other reason, this episode would be memorable for the first regular appearance of Martin Short, previously an SCTV staff writer and unbilled bit player. The highlight of the proceedings is the fund-raising "Battle of the PBS Stars" co-anchored from the playing fields of Yale by Howard Cosell (actually Eugene Levy) and Dick Cavett (Rick Moranis). Main events include a boxing match pitting Mister Rogers (Short) against Julia Child (John Candy); Joan Sutherland (Catherine O'Hara) and Beverly Sills (Andrea Martin) competing in the high jump; Carl Sagan (Dave Thomas) taking the viewers behind the scenes at "Cosmos" -- and nearly getting killed by a falling stage weight; and William F. Buckley (Joe Flaherty) making Conservative converts of Jane Fonda (O'Hara) and Tom Hayden (Short). Additionally, the SCTV Movie of the Week presents "I Was a Teenage Communist," in which naïve teenager Eddie Davis (Short) is suckered by the Commies, then turns into a werewolf after listening to musical guests The Dave Edwards Band. And footballer "Mean" Joe Greene hosts a "Masterpiece Theater" selection of his TV commercials, including (you guessed it!) "The Big Dude and the Kid."
