Hef joins the Not Ready for Prime Time Players -- John Belushi, Dan Aykroyd, Gilda Radner, Bill Murray, Laraine Newman, Garrett Morris and Jane Curtin -- to host a third season episode of the groundbreaking late-night show. During his monologue, Hef brought down the house with a rendition of Thank Heaven for Little Girls. Other highlights of the show include Hef showing Jane Curtin the wonders of his infamous round bed, Hef's delivering the Playboy Philosophy in Socratic garb and a space spoof in which Hef played Captain Macho. Legendary comic Andy Kaufman was the special guest, and Libby Titus was the musical guest.
