Drinking Buddies

Two men are sitting next to each other in an Irish-style pub in New York City. They both order pints of Guinness. One of them turns to the other and says "So where are you from, then?"

- I'm from Ireland.

- Me too! I'll drink to that.

They both finish their pints and order two more.

- Where in Ireland are you from?

- Dublin.

- Me too! I'll drink to that.

They both finish their pints and order two more.

- Where in Dublin are you from?

- The East Side.

- The East Side? Me too! What a coincidence! I'll drink to that!

They both finish their pints and order two more.

- Where on the East Side are you from?

- McDonagh Street.

- Me too! This is incredible! I'll drink to that.

As the bartender pours them another two pints, another customer at the bar says to him, "That's amazing! I can't believe they're from the same street in Dublin. What's going on?"

"Oh, it's nothing amazing," says the bartender, "it's just the Ferguson twins getting sloshed again."
