Another Irish joke

[Ninja Mania]

Before you start, some of the best work mates I have ever worked with are irish, but,

Two men were sitting next to each other at Murphy's Pub.
> After awhile, one guy looks at the other and says, "I can't
> help but think, from listening to you, that you're from
> Ireland ."
>
> The other guy responds proudly, "Yes, that I am!"
>
> The first guy says, "So am I! And where about from Ireland might you be?"
>
> The other guy answers, "I'm from Dublin , I am."
>
> The first guy responds, "So am I!"
>
> "Mother Mary and begora. And what street did you
> live on in Dublin ?"
>
> The other guy says, "A lovely little area it was. I lived
> on McCleary Street in the old central part of town."
>
> The first guy says, "Faith and it's a small world. So did
> I! So did I! And to what school would you have been going?"
>
> The other guy answers, "Well now, I went to St. Mary's,
> of course."
>
> The first guy gets really excited and says, "And so did I.
> Tell me, what year did you graduate?"
>
> The other guy answers, "Well, now, let's see. I graduated in 1964."
>
> The first guy exclaims, "The Good Lord must be smiling down upon us! I can
> hardly believe our good luck at winding up in the same bar tonight. Can you
> believe it, I graduated from St. Mary's in 1964 my own self!"
>
> About this time, Vicky walks into the bar, sits down and orders a beer.
>
> Brian, the bartender, walks over to Vicky, shaking his head and mutters,
> "It's going to be a long night tonight."
>
> Vicky asks, "Why do you say that, Brian?"
>
> "The Murphy twins are drunk again."
