Heisenberg is pulled over by a policeman whilst driving down a motorway.
The policeman gets out of his car, walks towards Heisenberg's window and motions with his hand for Heisenberg to wind the window down, which he does.
The policeman then says 'Do you know what speed you were driving at sir?'
Heisenberg responds 'No, but I knew exactly where I was.'
