Shot noise: current made of discrete charges fluctuates with spectral density SI = 2qI. Its size reveals the charge of the carrier.

The joke: Shot noise exists only because e is not zero; physicists measure fractional charge (e/3) this way. The slogan on the mug reads CHARGE COMES IN LUMPS. SO DOES PROGRESS.
