One sunny day in Ireland, two men were sitting in a pub, drinking some Guinness, when one turns to the other and says "You see that man over there? He looks just like me! I think I'm gonna go over there and talk to him."
So, he goes over to the man and taps him on the shoulder. "Excuse me sir" he starts, "but I noticed you look just like me!"
The second man turns around and says "Yeah, I noticed the same thing. Where you from?"
"I'm from Dublin" came the reply.
"Me too! What street do you live on?"
"McCarthy street"
The second man replies, "Me too! What number is it?"
"162" the first man replies.
"Me too! What are your parents names?"
"Connor and Shannon"
The second man, almost dumbfounded says, "Mine too! This is unbelievable!"
So, they buy some more Guinness and they're talking some more when the bartenders change shifts. The new bartender comes in and goes up to the other bartender and asks "What's new today?"
"Oh nothing much, the Murphy twins are drunk again though."
