Heisenberg, Schrodinger and Ohm 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 doing 55 in a 35." 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, asshole!" shouts Schrodinger.
The cop moves to arrest them. Ohm resists.
