From the Corner:
For Heisenberg's birthday, I thought (although I was not sure) that you would enjoy my favorite Heisenberg joke: Werner Heisenberg, out for a drive, is stopped for speeding by a policeman. 'Do you know how fast you were going?!,' yells the irate cop. 'No,' replies Heisenberg, 'but I know exactly where I am.'"
They think Heisenberg's birthday was yesterday... but can anyone really know that?
