Three Irishmen having a pint in a pub.
One says 'great place this, buy one drink and you get a free packet of crisps with the second!'
The second guy says ' There's a pub in my village, where if you buy one drink the second is free'
The third guy says 'Well I hear that there is a pub in my village whre if you buy one drink you get the next six free, and after that you can go out the back for a free shag!'
The others are incredulous, 'thats amazing' they say, Have you been?
Not yet! he says, but my sister has.
