As an insurance agent I get to hear all kinds of strange stories, particularly about things people ran over with their cars. I had someone flip a van after hitting a 6' gator. I've had quite a few busted oil pans from armadillos. I've seen totalled cars from hitting dogs, pigs, and deer. But the worst damage I've ever seen from road debris was someone in a saturn that ran over a fire extinguisher. When that thing exploded it took out passenger floor board and seat as well as the entire front wheel assembly.
Funniest though was a duck. A friend of mine hit a duck, saw it but couldn't avoid it. The people in the car next to her kept pointing to her front end, she's keeps nodding and saying yes, sorry I killed a duck. Finally she pulls over to see what they're talking about. The poor duck is stuck in the grill still alive and quacking at her. She slowly made her way to a repair shop where they cut the duck loose. The duck fussed at them a few times then waddled back to the canal across the street...

BTW, if you haven't read this before you're in for a treat...
