An Irishman, an Italian, and a Polish guy are in a bar. They
are having a good time and all agree that the bar is a nice
place.
Then the Irishman says, "Aye, this is a nice bar, but where
I come from, back in Dublin, there's a better one. At
MacDougal's, you buy a drink, you buy another drink, and
MacDougal himself will buy your third drink!"
The others agree that sounds like a nice place.
Then the Italian says, "Yeah, that's a nice bar, but where I
come from, there's a better one. Over in Brooklyn, there's
this place, Vinny's. At Vinny's, you buy a drink, Vinny
buys you a drink. You buy anudda drink, Vinny buys you anudda
drink."
Everyone agrees that sounds like a great bar.
Then the Polish guy says, "You think that's great? Where I
come from, there's this place called Warshowski's. At
Warshowski's, they buy you your first drink, they buy you your
second drink, they buy you your third drink, and then they
take you in the back and get you laid!"
"Wow!" say the other two. "That's fantastic! Did that actually
happen to you?"
"No," replies the Polish guy, "but it happened to my sister!"
