Here’s an IBM promotional film starring an early version of Jim Henson’s Cookie Monster.

The Coffee Break Machine was used for an IBM training film and performed on The Ed Sullivan Show in 1967 and on The Muppet Show a decade later. A proto-Cookie Monster wanders upon a talking coffee machine that has been set in “Auto-Descriptive” Mode. As the machine describes its parts, the monster eats them. Once the machine is finished, the voice of the machine from inside the monster tells him that he has activated the anti-vandalism program, which harbors the most powerful explosives known to man. The monster instantly combusts. The version on the Ed Sullivan Show is slightly different; in this version, the machine itself is an explosive device. [Source]
