Two men are drinking in a bar.
The first one asks: “Where are you from?”
“I’m from Ireland”, replies the second man. "Me too!", says the first man, delighted to meet a fellow countryman, "Let’s have a drink to Ireland!”
After the toast to Ireland, another round of questions starts, as the first man asks: “Whereabouts in Ireland are you from?" “Dublin”, comes the reply.
“I don’t believe it”, cries the first man. “I’m from Dublin too! Let’s have another drink to Dublin.”
Curiosity strikes and the first man asks: “When's your birthday?”
“1st April”, replies the second man. “This is unbelievable!”, the first man says. “I was born on April 1st too!”
Just then one of the regulars comes in and sits down at the bar.
What’s going on?”, he asks the bartender.
“Nothing much,” replies the bartender. “The O'Connor twins are drunk again."
