Dirty car

A man walks into a friend and see's that his friend's car is total loss and covered with leaves, grass, branches, dirt and blood.

He asks his friend, "What's happened to your car?"

"Well," the friend responses, "I ran over a lawyer."

"OK," says the man, "that explains the blood... But what about the leaves, the grass, the branches and the dirt?"

"Well, I had to chase him all the way through the park."
