A man stumbles up to the only other person in a bar and asks if he could buy him a drink. "Why of course", comes the reply. The first man then asks: "Where are you from?" "I'm from Ireland", replies the second man. The first man responds: "You don't say, I'm from Ireland too! Let's have another drink to Ireland !" "Of Course", replies the second man. Curious, the first man then asks: "Where in Ireland are you from?" "Dublin", comes the reply. "Feck thats spooky, I can't believe it", says the first man. "I'm from Dublin too! Let's have another drink to Dublin." "Absolutely", replies the second man.
Curiousity again strikes and the first man asks: "What school did you go to?" "Saint Mary's", replies the second man. "I was in the fifth form in '62." "This is feckin unbelievable!", the first man says. "I went to Saint Mary's and I was in the fifth form in '62, too!"
About that time, in comes one of the regulars and sits down at the bar. "What's been going on tonight ?", he asks the bartender. "Nothing much," replies the bartender. "Oh, but the Murphy twins are drunk again."
