What's the worst "nest" you've found in an A-body?

I swore something made a mess under the original bucket seats in my 65, but it turned out to be the seat bun that had turned to the same stuff that flower arangements are stuck into: sort of a powdered foam. **** was flying everywhere when I drove with the windows down. I climbed a pole to get to a telephone terminal. When I opened it, a rat jumped out about 6 feet to the nearby tree.
