The 'Muppets' creator used to work on TV commercials for Wilkins Coffee back in the day (from the late '50s through the early '60s) in which he used early versions of puppets he had to peddle java for the food brand.

One guy wrote, "can't stop laughing at these early jim henson commercials where one guy just kills another for not liking wilkins coffee." Yep, that's the gist of these throwback spots -- it's basically one Henson puppet murking another puppet who refuses to drink the Wilkins.

Somebody uploaded a full 14-minute clip of all the Henson Wilkins ads, and it's eye-opening.

Just check out this early 'Muppets' toy commercial, where the dolls threaten violence onto the viewers if they don't buy them.
