An Irishman walks into a bar and orders a beer. He raises his glass and says, "This is for me home in Ireland."
Another guy in the bar yells out, "Hey, I'm from Ireland as well. Let's have another round for Ireland and the great city of Dublin."
The second guy yells out, "Hey, I'm from Dublin, too! Let's have another round for Dublin and me dear old mother, Gladys."
The first guy yells out, "Hey, me mother's name is Gladys, too!"
As the two guys are crying and hugging each other, someone walks into the bar and asks the bartender, "What's going on?"
The bartender says, "Nothing. The O'Grady Twins are drunk again."
