An unnamed Muppet The LaChoy Dragon and in a 1960s commercial for LaChoy Chow Mein.
It doesn't get much better than these...more classic 1960s Muppet commercials for Royal Crown Cola, Munchos (potato crisps), and LaChoy Chow Mein. Sesame Street fans should watch the Munchos spots for a then-unnamed monster puppet that went on to develop a famous taste for cookies. Also, the birds in the Royal Crown commercial were the inspiration for Big Bird and Little Bird.
