A man walks into a bar at 7 o'clock and orders three beers. The waitress asks "Why three beers?" and he replies "One for my brother in England, one for me, and one for my other brother in Ireland. We all go to a pub at 7 o'clock and order three beers, just like we used to before we got separated." he explained. "Oh, I see." she replies.
The next day the same man walks in and orders three beers again. This goes on for about three week.
And then one day he comes in and he only orders two. "Oh I'm so sorry." says the waitress. "For what?" replies the man. "Well since you normally order three beers, one for each of your brothers and you and now your only ordering two, I assume one passed away." she says.
"Oh no! Dear!" he says and starts to laugh. "I just quit drinking!"
