The Irishman and the three beers

An Irishman moves to the us, on his first day he goes looking for a bar and finds one he likes once he enters he orders three beers, he drinks the beer, pays and leaves. He keeps doing this for a week then the bartender asks him:

* Sir why do you always drink three beers at once instead of ordering one beer at a time?

To what the Irish answers:

* Well my brothers and I used to have a daily beer back in Ireland and now that live here I drink mine and one for each of my brothers

The bartender leaves the man alone and he becomes a regular going daily for years, everyone who visited the bar knew about the Irishman and his three beers but one day he enters the bar and orders 2 beers, everyone gets quiet and the bartender says:

* I'm sorry for your loss, your brother is in a better place now

To what the Irishman responded:

* My brothers are fine I just quit drinking
