There's an old joke that goes, "A logician's spouse says, 'Please go to the store and buy bread. If they have eggs, buy a dozen.' The logician returns with twelve loaves of bread."
The other week I called up Mountain University's maintenance department.* "Our dishwasher's gasket is coming out and, er, kind of rotting," I said. "Can you replace it?"
"Sure," they said.
Two weeks later, I came home to find a new dishwasher.
