A very drunk Irishman met a prostitute up a very dark alley.
He asks "How much for full sex"?
She says £20
"Okay feels like you have a lovely ass done deal"
They get down to business and are moving along nicely.
Suddenly a policeman appears shining his torch at them.
"Whats going on here"? he asked.
"Oh nothing I am just having sex with my wife officer"
"I did not know she was your wife paddy" said the officer.
Paddy shouted back
"Neither did I till you shone the fuckin torch in her face"!
