I'm sure The Simpsons fanatics in the peanut gallery knew all about it, but I didn't know until today that Moe Szyslak is based on an actual person. An that whole prank call running joke that's been with the show since the start? Yup, a complete homage to what appears to be the mother of all crank callers.
Personally I don't go for the modern stuff Stern's gang pulls, but I have to admit these ancient classics are damned funny.
