A man visits a friend and sees that his friend's car is a total wreck, covered with leaves, grass, branches, dirt, and blood.
He asks his friend, "What happened to your car?"
"Well," the friend replies, "I ran over a lawyer."
"Okay," says the man, "that explains the blood... But what about the leaves, grass, branches, and dirt?"
"Well," the friend says, "I had to chase him all the way through the park."
