Another way to not get coffee

I thought that many years ago I had discovered (by "denial and error" as Ricky from the Trailer Park Boys would say) all the ways of not getting coffee from my automatic drip coffee maker:

1. Not filling the carafe with water from the faucet;
2. Filling the carafe with water from the faucet, but not pouring that water into the reservoir of the coffee maker;
3. Putting water in the reservoir, but not putting coffee in the filter basket;
4. Putting water in the reservoir and coffee in the filter basket, but forgetting to turn on the coffee maker; and
5. Putting water in the reservoir and coffee in the filter basket, turning on the coffee maker, but not plugging in the coffee maker.

I thought that was it, a 5-item list, but yesterday morning, while perhaps more groggy than usual, I discovered a sixth method of not getting coffee:

6. Putting water in the reservoir and coffee in the filter basket, turning on the plugged-in coffee maker, but pouring into an upside-down mug.
