An old man is sitting at the bar. Another elderly gentleman comes in, nods to him and orders a Guiness from the bartender.
First old man: "Faith, laddie, I can tell by yer accent that you're from the Auld Sod. Imagine two of us in this same bar from Ireland. Let's have a drink on it!"
Second old man: "Yes, let's. Are ye a Dublin man?"
First old man: "The very thing! Born and bred on O'Connell Street."
Second old man: "Ye don't say? I was, myself! It's not every day two old laddies from O'Connell Street meet up like this. It's for sure we must be havin' a drink on it!"
First old man: "Ye didn't go to school at the Brother's, did ye?"
Second old man: "I did indeed! D'ye remember Brother Finn? What a beatin' he gave me on a regular basis. It's a drink we'll be havin' to Ol' Brother Finn!"
After much conversation and more beer, they discover that they also both had a sister who had been a nun, a brother named Connor, and a great love for the horses.
This goes on for a while and another customer remarks to the bartender that it was certainly a coincidence that two elderly men who came from the same place would end up meeting in a bar in Las Angeles. "Naw," says the bartender, "Nothing to get excited about. It's just the Maloney twins drunk again."
