Heisenberg and Schrodinger are in a car. They get pulled over.

Heisenberg is driving, and the cop asks him, “Do you know how fast you were going?”

“No, but I know exactly where I am,” Heisenberg replies.

The cop says, “You were going 140 km/h, were only 120 is allowed”

Heisenberg throws up his hands and shouts, “Great! Now I’m lost!”

The cop thinks this is suspicious and orders him to pop open the trunk. He checks it out and says, “Do you know you have a dead cat back here?”

“We do now, you bastard!” shouts Schrodinger.
