What stuff have you found in your cars from previous owners?

A police accident report in the trunk. Father took his kids to get ice cream, and one daughter was bad so she was made to sit in the car while everyone else got ice cream. Dad left keys in the car (now it's my car) and the bad daughter started it, put it in drive and floored it. It ran over the curb/island and hit the car parked on the other side. Then she put it in reverse and floored it again, but it was stuck and wouldn't move. I forget how much damage it said was caused to my car (though it was all fixed when I got it).
