What's the weirdest thing you've found in a car?

I just picked up a '73 Dart Sport roller - planning on transferring the driveline from my crashed '73 Duster bracket car. While cleaning out years of all sorts of mess, I popped off the door panel and found, inside... a hefty pile of credit cards, membership cards, gift cards, etc. All were from 1999. More interestingly, EVERY SINGLE ONE OF THEM HAD A DIFFERENT NAME ON IT! Clearly, this old girl has some stories to tell.

What are some of the weird things you all have found in recently acquired A-Bodies?
