3 irishmen were stranded at sea.
Through magic, they found a genie living inside their last water bottle.
The genie, of course, granted each of them the stereotypical one wish each.
The first irishman said "man, it's hot our here, I wish we had some shade"
POOF! a canopy appeared over the boat!
The second said "man, I wish we could get to shore faster"
POOF! An outboard motor appeared on the back of the boat!
While they were motoring along, the last one said
"Gee, I'm thirsty, I wish we had some beer."
POOF! The ENTIRE OCEAN was suddenly made of guinness beer!
The last irishman turned to the genie, "YOU DUMBASS!! Now we gotta piss in the boat!"
