Were it a Pika...it would be comical. Not only would the chirping be bothersome all the way home (really that would have to tell you to pull over). But once you were home you car key would disappear!
Now for something really odd. A friend had a snake in the car. It got out of the bag, but not the car.
It stayed in the car for 4 months until the car was taken to a auto-body shop. They had to take the back end of the car apart to get at it!
