Waiting.

[Homer runs out the clock sitting in anticiaption of the waiting period for his gun to be over.]
Waiting, for most of us, is synonymous with anxiety, fear, impatience, nail-biting, and in some instances, long bouts of drinking. Most of the time, waiting is innocuous: we wait for the train or the bus; we wait for our tank to fill up; we wait for our food to get to the table; we wait for the next drink in our waiting-driven drinking bout.
