An Old Joke

(related to yesterday's post)

A cop pulls a car over and asks to see a driver's license. He looks at it and asks "Dr. Heisenberg, do you know how fast you were going?" Dr. Heisenberg answers, "I have no idea. But I know precisely where I was."

Later the cop pulls a second car over, and after looking at the driver's license says "Dr. Schroedinger, I noticed you were driving erratically. Do you mind if I search your car?" Dr. Schroedinger gives him permission. After searching, he comes back to the driver's window. "Dr. Schroedinger, are you aware that there's a dead cat in your trunk?" Dr. Schroedinger says, "Well, there is now."
