Three guys stranded on an island find a genie's bottle washed up on the shore one morning.

She grants them a wish each. The American says "I've been on an island with two guys for 5 years, I'd like to be home in New York with my girlfriend". He vanishes.

The Aussie says "Same deal, with my girl back in Sydney" and he vanishes.

The genie looks at the Irishman impatiently and he says "Its going to be lonely here without them, I wish they were back."
