Following a moment of inattention by the Captain, a ship sank in the middle of the ocean. Two guys managed to inflate a rubber life raft and grab a box of provisions before the ship slipped gently below the surface. After floating under blazing heat for six days they ran out of food and water.
On the tenth day, bleary eyed and half dead from heat, thirst and starvation, they spotted a small object floating toward them in the water. As it drew near, they were ecstatic to find that it was an oil lamp (Oil Lamp, Brass, One. Genies for the use of). They grabbed the lamp and rubbed it. Out popped a tired old genie.
"OK, so you freed me from this stupid lamp, yadda, yadda, yadda. But hey, I've been doing this three wishes stuff for a long time now and quite frankly, I'm burned out. You guys get only ONE wish and then I'm OUTTA here. Make it a good one".
The first guy, without hesitation or thought blurted out, "Give us all the beer we can drink for the rest of our lives!!!"
"Fine," said the genie, and with a wave of his hand, the entire ocean turned into beer.
"Great move Einstein!" said the second guy, slapping the first guy in the head. "NOW we're gonna have to pee in the BOAT!"
