An Englishman sees a sign for a brothel.

So he goes in, pays his 20 quid, gets led through to the room at the
back where someone hits him over the head, knocking him out.

A Scotsman sees the same sign, goes in, pays, same thing.

Ditto an Irishman.

They wake up on a raft in the middle of the sea, out of sight of land.

"Oh my god, we're gonna die!!" panics the Englishman.

"Dinna fret, they'll send a helicopter out for us.", says the Scot.

"They bloody well didn't last year", says the Irishman.
