A guy walks into a bar and asks for three beers. The bartender puts them up and then watches the guy go through a peculiar ritual.
"Happy Birthday, Happy Birthday, happy birthday" Each time he says the word he drinks the beer. Then he pays and walks out.
One year later he enters the bar again and orders the same thing. The bartender watches him go through the same ritual. Curious, he asks the bloke why.
"Well" the guy says, "I have a friend in Ireland and a friend in Australia. We have our birthdays on the same day. We can't be together so we have agreed that on this day we will each go into our local pub and have a round of drinks for each other. We have been doing this for 55 years since we were 18"
The next year the man comes in and asks the bartender for two beers. The bartender, a bit taken aback, places two beers in front of the guy and watches him say "happy birthday, happy birthday!"
The bartender asks "so which one died?"
"No one."
"But you only ordered two drinks!"
"Yeah, well, I've given up drinking."
