Chasing the Lawyer

A man walks into a friend and sees that his friend's car is a 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 into 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 through the park."
