This is one of my all-time favorite sketches. It was on The New Show, a short-lived sketch show on NBC. This appeared on January 13, 1984 and featured John Candy and Valerie Bromfeld, with appearances by Dave Thomas, Carrie Fisher, and Paul Simon.
This sketch is from the Bill Tush show that aired in 1982 on Superstation WTBS out of Atlanta. It features Terry Turner, who with wife Bonnie (also on the show) went on to work as a writer on SNL, then developed That 70s Show and 3rd Rock From the Sun. Also in the sketch is Eddie Lee. A follow-on pseudo promo features Bill Tush and Jan Hooks (of SNL and 3rd Rock fame).
