Heisenberg was driving his new Merc on the autobahn when he was pulled over for high speeding by a police officer. "Do you know what your speed was!", the officer exclaimed. "Well, I don't know that, but I know exactly where I am", the snooty scientist replied.
"You smartass", the officer screamed. He started beating the snout out of Heisenberg. Unbearable with pain, Heisenberg asked him, "How long does this going to take?". With a grin on his face, the officer explained, "Well, I don't know anything about that, but I know exactly how much effort I am putting in"
