St Patrick's Day gag

Dollfaces,

I couldn't let the biggest day in the calendar go by without a decent St Paddy's Day joke...so here goes, my little munchkins. Peris xxx

A man stumbles up to the only other patron in a bar and asks if he could buy him a drink.

"Why to be sure," comes the reply.

The first man then asks: "Where are you from?"

"I'm from Ireland," replies the second man.

"You don't say, I'm from Ireland too! Let's have another round to Ireland," says the first bloke.

"Why not," replies the second man.

Curious, the first man continues: "Where in Ireland are you from?"

"Dublin," mutters the 2nd guy.

"I can't believe it," says the first man. "I'm from Dublin too! Let's have another drink to Dublin."

"Great, why not!" replies the second man.

Curiosity again strikes and the first man asks: "So, what school did you go to?"

"Saint Mary's," says the second chap. "I graduated in '62."

"This is UNBELIEVABLE!" the first bloke says. "I went to Saint Mary's and I graduated in '62, too!"

Just then, in comes one of the regulars and sits down at the bar.

"What's been going on?" he asks the bartender.

"Ach, nothing much," he chirrups. "The O'Malley twins are drunk again."
