A very attractive young lady speech therapist was getting nowhere with her stammer action group of three young men, consisting of an Englishman,a Scotsman and an Irishman.
She had tried every technique in the book without the slightest success. No-one was improving.
Finally, thoroughly exasperated , she said "Look. We seem to be getting nowhere. I'm going to give you three guys some extra special incentive and motivation. The first of you to be able to tell me, without stuttering, the name of the town where you were born, I will have wild and passionate sex with you right here and now in this room, until your muscles ache and your eyes water. I'm serious about this. So, who wants to go first?"
For a moment, you could have heard a pin drop in the ensuing surprised silence and then the Englishman eagerly blurted out “b-b-b-b-b-b-Birmingham!”.
"Oh, I'm sorry. That’s no use, Trevor." said the speech therapist "Who's next?"
The Scotsman said “p-p-p-p-p-Paisley!”
"Oh dear. That’s no better. There will be no sex for you either I'm afraid, Hamish." said the speech therapist "How about you Paddy?"
The Irishman took a deep breath and eventually blurted out "LONDON!"
"Brilliant Paddy!" said the speech therapist, delighted, and immediately jumped up, ripped off her clothes and Paddy's clothes, and then set about living up to her promise.
After 15 minutes of exceptionally steamy sex the couple paused for breath and Paddy gasped and then said, “d-d-d-d-d-Derry”.
