One of the first muppets was a murderous psychopath. Cookie Monster used to eat snack crackers, back when he still had teeth. Kermit used to sing about the wonders of cooked bacon!
After first being introduced on a Washington DC television show called Sam and Friends, the Muppets started branching into commercial work. Starting in 1957 to advertise coffee, Muppets Wilkins and Wontkins acted out dozens of violent slapstick skits that would make Moe, Larry, and Curly wince.
Wilkins was a character similar to Kermit the Frog, but with round eyes. Wontkins was a bit more abstract-looking. In most of the commercials, Wontkins would be the victim of some horrible accident or abuse, triggered or inflicted by Wilkins. Guns, guillotines, and bombs often came into play.
