Check out these great spots for Wilkins coffee. They were made by Jim Henson back in the late 50s before Muppets fame. Each spot was 10 seconds and tightly crafted with an 8 second pitch and 2 second product shot, apparently he made 179 of them. They're a bit weird and sadistic but funny and direct.
This is what Jim had to say about them “We took a different approach,” “We tried to sell things by making people laugh.” Amen to that.
