Irish man goes into a pub and orders 3 pints of Guinness at the bar. The bar looks at him a bit oddly but serves him with his chosen drink. The Irish man then goes off with his 3 pints and sits at a table, drinking from each pint glass one after the other before returning to the bar to order 3 more pints. This goes on for most of the evening untill the barman pipes up and asks "Why do you buy and drink 3 pints of Guinness like that ?" The man replies "Well me and my brothers used to go out drinking every Friday night before I moved away and I said I would carry on with the tradition even though I've moved" The barman nodded and served another 3 pints. This went on for many months and became normal practice until one day the Irish man comes in and order only 2 pints of Guinness - everyone in he pub goes silent as the watch him walk over to his usual table. Thinking the worst, the Barman goes over to his table and says softly "I'm sorry for your loss" the Irish man looks up and says "Don't be silly, none of my brothers have died, I've given up drinking"
