An Irishman strolls into a pub in Dublin and asks for three pints of Guinness. He proceeds to take a swallow from each glass and going back and forth, he eventually empties the glasses.

The barman has watched this with curiosity. He comes over and says:" You know, I can set you up with one pint at a time and you can have a cold one each time". The Irishman explains: " Oh, thanks, but you see I have a brother in Australia and another one in the States. We agreed that each Saturday night we would drink together - and that's what we are doing."

The bar man thinks to himself about what a nice tradition that is. Thus, each Saturday night, the Irishman comes in and the routine is repeated.

However, one Saturday night the Irishman comes in and orders only two pints.

The barman expresses his sympathy for the Irishman's great loss. The irishman says smilingly: " Oh, no, my brothers are fine!. I just quit drinking".
