Well, in 1980, I was living in Ardsley, NY, finishing high school, and my mother came to visit and wanted to see a show in NYC. I told her we should take the train, but she insisted that I drive her. It was a Friday night, and while I no longer recall how much I paid in tolls, I do remember it cost $50 to park (remember, this is 1980!) for 4 hours.
It is a great joke though.
