Heisenberg and Schrodinger are driving down the highway at a prodigious rate of speed. As they pass mile marker 34, a state trooper hits them with a radar, chases them down, and pulls them over.
The trooper walks up to the driver's side window and finds Heisenberg behind the wheel.
Trooper: "Sir, do you know how fast you were going when you passed that mile marker?"
Heisenberg: "Well, I can't because I now know where I was."
The trooper detains them and does a consent search of the car. In the trunk he finds a dead cat. He goes back to his car where the two arrestees are sitting in the back seat.
Trooper: "Did you know there is a dead cat in the trunk of your car?"
Schrodinger: "Well, now I do."
