An Irish man walks into a pub and says to the bartender, "Give me three pints of Guinness please".
So the bartender brings him three pints and the man proceeds to alternately sip one, then the other, then the third until they're gone.
He then orders three more.
The bartender says, "Sir, you don't have to order three at a time. I can keep an eye on it and when you get low I'll bring you a fresh cold one."
The man says, "You don't understand. I have two brothers, one in Australia and one in the States. We made a vow to each other that every Saturday night we'd still drink together. So right now, my brothers have three Guinness beers too, and we're drinking together." The bartender thought that was a wonderful tradition.
Every week the man came in and ordered three beers.
Then one week he came in and ordered only two. He drank them and then ordered two more.
The bartender said to him, "I know what your tradition is, and I'd just like to say I'm sorry that one of your brothers died."
"Oh, my brothers are fine", the Irishman said---- "I just quit drinking."
