Bernie say it ain't so...
Bernie didn't steal this joke. This joke has been around since the early 70s. My uncle told it to us when I was around 8 years old. The only difference is the punchline was: "H h he w w was f f f fucking w w with m m me!"
Just like Robin Harris' "The piccolo player is a motherfucker" joke. That joke has been around since the 50s.
It still diminishes him to know that he was just the guy who popularized it but not the guy who conceived it.
Just the way it was pre-Internet, the game has changed...
