That slang term 'fuzz'

Back in that decade there was a joke that became passe very quickly...

Q:What's black and white with fuzz inside?
A:A police car.

The joke wasn't in circulation for very long at all before it was at the point that if you tried to tell it, the person you were telling it to immediately answered with the punchline.
I think it's been so long since the term was in use that if you told the joke today you'd get..."I don't get it."
We'll probably always hear "cop", I even still hear "pig" now and then. But "fuzz"? I don't think I've heard it since the 1970's.

Great minds run in the same channel, and fools think alike.
