An Irishman was walking home late at night and sees a woman in the dark shadows.'Thirty quid,' she whispers.

Murphy had never been with a hooker before, but Decides what the hell, it's only thirty quid.
So they hid in the bushes.

They're wildly and passionately entwined for a minute when all of a sudden  a light flashes on them.
 

It is the police.

'What's going on here, people?' asks the cop.  'I'm making love to me wife,' Murphy answers sounding
Annoyed.

'Oh, I'm sorry,' says the cop, 'I didn't know.'

'Well, neidder did I, til ya shined that bloody light in her face!'
