My new favorite joke ever.

[aristokat]

Werner Heisenberg is driving to a lecture appointment at the Institute For Advanced Studies, and gets pulled over by a cop for speeding. The cop walks up to the driver's side window and says, "Sir, do you know how fast you were going?" To which Heisenberg says, "No, but I know exactly where I am."

Hee hee.

Runner up: Einstein is lost in a New York subway terminal. He sees a train pulling up, turns to a bystander, and says, "Excuse me sir, does Fifth Avenue stop at this train?"

hee hee hee.
