Werner Heisenberg and Ernst Schrodinger are driving down the road late one night, and they are stopped by a cop.
Heisenberg rolls down the window and says, “evening officer”.
The cop asked, “Do you know how fast you were going?”
Heisenberg says, “No, but I knew exactly where I was.”
The cop says, “You were going exactly 143 kilometers per hour.”
Heisenberg says, “Great! Now we’re lost!”
The cop asks, “Do you mind if I look in your trunk?”
Schrodinger says, “Go ahead. All we have in there is a cat.”
The cop looks in the trunk and says, “Sorry to tell you, but your cat is dead.”
Schrodinger sighs and says, “Well _now_ he is!”
