Q: How many Heisenbergs does it take to change a light bulb?
A: If you know the number, you don't know where the light bulb is.
A: If you know how many, you can't know if they've done it yet.
A: If you want to know how many, you can observe them as they
come in the door. But if not observed, they come in waves.
A: The probability that the light bulb will actually be changed
in any time interval is independent of how long you've been waiting.
