Super Password is airing episodes from February 1987, when NBC had a "Car-Azy February" promotion. On SP, Scrabble and probably at least one other show, they showed puzzles, and viewers sent in postcards with their solutions to win a car. Today's SP made reference at the end to not having one. This is something one would think they'd cut when they're making room for the extra commercials! Glad I got to see it.
Incidentally, numerous shows in that promotion got pre-empted by the Iran-Contra hearings. I think the announced rule was that you had to solve all five puzzles, but because of the pre-emptions, they just let anyone who got one puzzle right into the drawing. (If, as I recall, each show was giving away five cars, I would simply have had five separate drawings, each one limited to people who got a specific day's puzzle right.) It would be ironic if today's show was one of the pre-emptions, since they had this puzzle: ARMS ... IRAN ... SCANDAL ... LIEUTENANT ... COLONEL.
