When I was a little 1980s kid, my family got rid of a malfunctioning wall-mounted rotary phone which had been installed there since time immemorial. I asked if I could keep it and my mom said no, but she did let me exercise my curiosity by taking it apart to see what the innards were like.

I kept the dial, and it still lives on a shelf of mildly-interesting things in my house. It still spins, though the recoil speed is way slower than it should be

(I also grew up to be a phone phreak.)
