An Irishman, an Englishman, and a Scot are sitting in a bar. They order a round of beers. The Scot comments, "In my hometown pub in Aberdeen, when you order 3 pints, they give you a fourth for free."
The Englishman, not to be outdone, replies, "That's nothing. At my favorite pub in Sheffield, they give you a free pint for every pint you order."
"That's nothing," responds the Irishman. "Back home in Galway there's a pub that gives special customers free pint after free pint. And then you can go upstairs and have sex."
"Really?" exclaim the two others. "Has that ever happened to you?"
"No," says the Irishman. "But it happens to me sister all the time."
