Three guys are standing outside a pub. An Englishman, a German, and a Scotsman.
British guy says, "In England, you can walk into any pub, and for every beer you buy, you get one for free."
German guy says, "That's nothing. In Germany, you can walk into a pub, and for every beer you buy, you get two for free!"
Scotsman says, "You guys are full of it. You can go to a pub in Scotland, and as soon as you walk in the door, they'll hand you a pint for free. When yer done with that, they'll hand you another, for free. And when yer done with THAT, they'll hand you another, for free. And when you're all drunk, they'll take you upstairs and have sex with you, for free!"
The Englishman and the German look at each other, then to the Scot and say, "Really? You've experienced this?"
Scotsman says, "No. But it happened to me sister twice!"
