Reminds me of the story of Seamus who was walking back home one...

Reminds me of the story of Seamus who was walking back home one night after a Guinness or three. He walks past a bush, and hears a voice "20 quid!". Paddy stops, and thinks a bit - best as he can in his inebriated state. He'd never been with a hooker before, and was indeed tempted by this unexpected opportunity. Why not, he thinks, and checks his wallet. Sure enough, there was two 10 pound notes, and the decision was made. He joins her behind the bush, passes her the cash and they get into it. Shortly after they get started, a paddy on the beat hears the commotion and goes to check it out.
"So what's going on here, hey?"
"If you don't mind, I'm making love to me missus!"
"Oh, sorry sir, I didn't realise she was your wife!"
"Neither did I until you shone that light in her face..."
