Schroedinger and Heisenberg were driving down the road when they got pulled over by a police officer. The officer asked Heisenberg, "Do you have any idea how fast you were going?"
Heisenberg responded, "No, but I know exactly where I am."
The officer found this suspicious, so he asked to search the vehicle. Upon popping the trunk, he says, "Did you know that there is a dead cat in here?"
Schroedinger answered him, "I do now."
