Small World

There were Two guys at a bar. They were making small talk and realized a couple of interesting things.. this is how their conversation went.
Guy 1: Yah..I'm originally from Dublin, Ireland
Guy 2: REally?! Me too!
Guy 1: I went to O'Malley Highschool.
Guy 2 : I did too! What year did you graduate?
Guy 1: 1988!
guy 2: Same here!

A guy sitting next to them was amazed how they grew up together and didnt know it. He asked the bar tender, who was friends with both of them if the two irish guys knew eachother.
The bar tender replied, " Yeah. It looks like the Donohue Twins are drunk again."
