Aibo's got nothing on the 1960s robot dog Gaylord. It's another Marvin Glass wonder, and Bedazzled has the TV commercial for it. Caution: contains jingle that has earworm qualities.

UPDATE: Steve Doggie-Dogg says: "The jingle for the Gaylord commercial was written by the
cartoon music genius, Raymond Scott. (Powerhouse, Dinner
Music for a Pack of Hungry Cannibals, etc.)"
