An Irishman, a Scotsman,and an Englishman are having a drink at a bar.
The Engishman says:there is a pub back home in England that gives you the 4th drink for free after you buy the first three.
The Scotsman says:yes ,back in Scotland we have a pub that does the same thing , but you only have to buy the first 2 drinks and they give you the 3rd one for free.
The Irishman says: there is a pub in Ireland that gives you the 1st drink for free, then gives you the 2nd drink for free , then gives you the 3rd drink for free, then gives you the 4th drink for free, and then you can go upstairs and have all the free sex you want.
The Scotsman and Englishman look at the Irishman in amazement and ask:have you ever went there and done that?
The Irishman says: no, but my sister has.
