The gentle lapping of beer on the hull

A joke in Haiku:

Two men were adrift
Dramatic escape from a
Burning freight vessel.

Rummaging madly
Through the boat's supplies they found
A dingy old lamp.

Secretly hoping
A genie'd appear, one of
Them polished the lamp.

And one did come forth
This particular genie
Stated quite clearly:

That she could only
Deliver one wish, and not
The usual three.

With barely a thought:
"Turn the ocean into beer!"
The man blurted out

Clapping her hands with
A deafening crash, the sea
Was plainly transformed

And truly the sea
Had become the finest brew
Sampled by mortals

And at the same time
The genie vanished to her
Freedom from the lamp.

The gentle lapping
Of beer on the hull broke the
Stillness in the boat

The two men sat and
Considered their circumstance
When one of them said:

"Great, now we have to pee in the boat!"
