An Irishman living in Boston visits a bar, and orders 3 beers.
He drinks one.
Drinks another.
Then the 3rd.
He does this all night.
The barman is curious , and asks what's up.
"Oh, I miss my 2 brothers back home, Seamus and Paddy. This is my way of sharing a drink with them."
A few months later, same guy, same bar, same barman, but this time he orders 2 beers all evening.
Batman is curious again, and asks:
"I see you're ordering 2 beers only. I hope nothing untoward has happened to Seamus or Paddy?"
"Nope", the customer replies, "it's me. I've given up drinking."
