When I was in grade school and high school, people my parents age used to type these up and pass them onward until the paper wore out. ( I remember in 5th grade an "old maid schoolteacher" confiscated one from a boy and was horrified to learn that his mother not only let him read her jokes, but had typed him his own copies.) Then, first mimeograph machines, then copiers allowed folks to keep one and share the copies. Now, the jokes make the rounds faster on the internet, but sometimes one stongly resembles a very old joke.
But you knew that all ready.![]()
