"Well JD, since our next stop is not within walking distance, we'll have to take a car to get there. I notice that someone has left their car unlocked. This is a bad idea since it makes it easy to steal."

"Hey, I've got an idea. Let's drive the car around and find the owner so we can warn them about this unsafe practice."

"I don't think we have that much time, JD. Let's just take the car and drive to our next stop."

"You're right Mark. By the way, what IS our next stop?"

"That's a surprise."
