Jokes paralleling real life

My best friend recalled today a famous musician's joke whose refrain pertains to so many things:
A man steps into a cab in New York City and asks the driver, "How do you get to Carnegie Hall?" The cabbie replies, "Practice, practice, pratice!"

Tomorrow, when I try to retell the joke, it'll probably come out something like this:
A man hails a cab in New York City and tells the driver, "To Carnegie Hall."  The cabbie replies, "Practice, practice, practice!"  As the passenger stares, the cabbie adds, "Hey man, did you know that Carnegie was related to Lizzie Borden? I heard it on TED."
