100 years ago an American joke was spawned from the back rooms of Vaudville. In the day people auditioned for the vaudville stage and you never knew what you were going to get. This is a version of the joke that was told only among comedians in private and has evolved over the years. https://www.youtube.com/watch?v=aGA0dIz9-Wk
Olde jokes don't do it for me.
