Two fishermen were adrift in their rented boat due to an engine failure. While rummaging through the boat's provisions, one of the men stumbled across an old lamp. Secretly hoping that a genie would appear, he rubbed the lamp vigorously. To the amazement of the castaways, a genie came forth. This particular genie, however, stated that he could only deliver one wish, not the standard three.
Without giving much thought to the matter the man blurted out, "Make the entire ocean into beer!" The genie clapped his hands with a deafening crash, and immediately the entire sea turned into the finest brew ever sampled by mortals.
Simultaneously, the genie vanished. Only the gentle lapping of beer on the hull broke the stillness as the men considered their circumstances.
One man looked disgustedly at the other whose wish had been granted. After a long, tension filled moment, he spoke: "Nice going idiot! Now we're going to have to pi** in the boat!"
