Actually, to be fair, I got out of a speeding ticket 3 years ago because I had an old crappy stethocope in my back seat. It was a weekend and I was driving to see a friend about 2 hours away, was speeding on the highway, and got pulled over.
Him: "So, son, I see that's a stethoscope back there. You in med school?"
Me: "Nah, not yet. I'm planning on it though. Right now I just help out at a doctor's office."
Him: "I see"
The cop took my info, went back to his car to write up the ticket, and appeared a normal length of time later.
Him: "Well son, I know you're pretty much screwed with how much money you're gonna owe in the long run, so I think we can look past this ticket for now. But don't let me catch you speeding ever again."
