"Castaways"

Two shipmates were adrift on a lifeboat in the middle of the ocean after their ship had sunk.  While searching through the boat's provisions one of the sailors stumbled upon an old brass lamp. 

Secretly hoping a Genie would appear he rubbed the lamp vigorously. To the amazement of both castaways, A Genie came forth.  This particular Genie, however, stated he could only deliver one wish, not the typical three we are accustomed to.  Without giving any thought to the idea the thirsty sailor blurted out …

“Make the entire ocean into rum!”

The Genie clapped his hands with a thundering crash, and immediately thereafter the entire sea turned into the finest rum ever sampled by mere mortals.  Simultaneously the Genie disappeared as quickly as he appeared.  Now only the gentle lapping of rum on the hull of the boat broke the stillness as the two considered their circumstance. 

The second sailor looked disgustingly at the first and said …

“Now you’ve done it! Now we’re going to have to pee in the boat!”
