The topic came up when the recent "next generation" Muppet movie was in theatres. People didn't understand what it was. No joke, I was showing them Sesame Street, the Muppet Show, Ed Sullivan, you name it. Nothing.
In their defense, the original Muppets seem to have had little or no presence in some countries. But I find it really funny when people say things like, "I was raised in Etobicoke."
