Ah Art.....Thanks for "coming clean" but we still love you.I was gonna' out you anyway as the joke has roots clear back to Vaudeville and probably beyond. The thing here is that a great joke, like a great song, needs to be repeated! Because it's old doesn't make it bad but the advent of radio and TV made the demand for new jokes very high. But a classic is always a classic. Groucho used to talk about that a lot and he was right.
