One night in a local pub, a man stumbled up to the only other patron in a bar and asked if he could buy him a drink.

"Why of course," came the reply.

The first man then asked, "Where are you from?"

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

The first man responded, "You don't say, I'm from Ireland too! Let's have another round to Ireland."

"Of course," replied the second man.

Curious, the first man then asked, "Where in Ireland are you from?" "Dublin," came the reply.

"I can't believe it, " said the first man. "I'm from Dublin too!" He continued, 

"Let's have another drink to Dublin."

"Of course," replied the second man.

Curiosity again struck and the first man asked, "what school did you go to?" 
"Saint Mary's," replied the second man. "I graduated in '62."

"This is unbelievable!" the first man said. "I went to Saint Mary's and graduated in '62, too!"

About that time, one of the regulars came into the bar and sat down.

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

"Nothing much," replied the bartender. "The O'Malley twins are drunk again!"
