Irishman walks into a bar, orders 3 pints of Guinness and drinks a sip out of each 1 in turn.
When he finished all 3, he comes back to the bar and orders 3 more.
The barman says to him, You know, a pint goes flat after a while, it would taste better if you drank 1 at a time.
The man replies, Well, I have 2 brothers. 1 in America, and 1 in Australia, and I'm here in Dublin. When we all left home, we promised that we'd drink this way to remember the days we drank together.
The barman says this is a nice custom, and leaves it there.
The man becomes a regular in the bar always drinking the same way.
1 day, he comes in and orders 2 pints. All the other regulars in the bar notice and fall silent.
When he comes back to the bar for the 2nd round, the barman says, I don't want to intrude on your grief, but I want to offer my condolences on your loss.
The man looks confused for a moment, then the light dawns in his eye.
Oh, no, he says, everyone is fine It's me-I've quit drinkin
