What’s a stereotype joke of people that come from your city/town?

I always think of this joke: A Welshman, an Irishman and a Scotsman go into a pub. They all have a severe stutter. "What's it to be?" asks the stunningly beautiful landlady. "Th th th th three pi pi pi..........." says the Welshman. Up steps the Irishman. "Three p pints of of of of gui gui gui........" Then the Scotsman tries. "Th th th th th th th......................" "Oh sod this!" says the beautiful landlady and walks away to serve someone else. She returns ten minutes later and asks if they are ready to order yet. "Th th th th three pi pi pi pi", stutters the Welshman "Three pints of gui gui gui gui........." tries Paddy. And then Scotty starts "Th th th th th th th...........". "Look" says the beautiful landlady, who loves a bet? "If any one of you can tell me where you live without stuttering I'll let you make love to me!" Quietly confident that no one will win, she turns to the Welshman. "Where do you live then boyo?" "C C C C CC AAAA.......Rrrrrrr.... ..." "No. You lose." says the beautiful landlady. Turning to the Scotsman, "Where do you live Scotty?" she asks,trying not to laugh. "E E E Ed Ed Edin Edin Edin Edinb." "No. You lose." says the gorgeous woman. "And Paddy, where do you live?" she purrs at the Irishman. "London" blurts out the Irishman. "Oh no!" says the landlady. A great cheer goes up in the pub and the landlady reluctantly takes him by the hand and leads him upstairs. Once in the bedroom she strips to her underwear, next she takes off her bra exposing a voluptuous bosom. Finally she slides off her panties then climbs into bed. Paddy with concentration furrowing his brow, climbs on and goes for glory, and then, right at the end he suddenly screams out........... ".......D D D Derry!!"
