The Man Who Orders Three Beers
An Irishman by the name of Paul McLean moves into a tiny hamlet in County Kerry, walks into the pub and promptly orders three beers. The bartender raises his eyebrows, but serves the man three beers, which he drinks quietly at a table, alone.
An hour later, the man has finished the three beers and orders three more. This happens yet again. The next evening the man again orders and drinks three beers at a time, several times. Soon the entire town is whispering about the Man Who Orders Three Beers.
Finally, a week later, the bartender broaches the subject on behalf of the town. "I don't mean to pry, but folks around here are wondering why you always order three beers."
"'Tis odd, isn't it?" the man replies. "You see, I have two brothers, and one went to America, and the other to Australia. We promised each other that we would always order an extra two beers whenever we drank as a way of keeping up the family bond."
The bartender and the whole town was pleased with this answer, and soon the Man Who Orders Three Beers became a local celebrity and source of pride to the hamlet, even to the extent that out-of-towners would come to watch him drink.
Then, one day, the man comes in and orders only two beers. The bartender pours them with a heavy heart. This continues for the rest of the evening -- he orders only two beers. Word flies around town. Prayers are offered for the soul of one of the brothers.
The next day, the bartender says to the man, "Folks around here, me first of all, want to offer condolences to you for the death of your brother. You know -- the two beers and all..."
The man ponders this for a moment, then replies, "You'll be happy to hear that my two brothers are alive and well. It's just that I, meself, have decided to give up drinking for Lent."

Samuel MolyneuxBorn 18 Jul 1689; died 13 Apr 1728 at age 38.British astronomer (Royal Observatory at Kew) and politician. Together with assistant James Bradley, he made measurements of abberation - the diversion of light from stars. They made observations of the star  Draconis with a vertical telescope. Starting in 1725 they had the proof of the movement of the earth giving support to the Copernican model of the earth revolving around the sun. The star oscillated with an excursion of 39 arcsecs between its lowest declination in May and its the highest point of its oscillation in September. He was unfortunate to fall ill in 1728 and into the care of the Anatomist to the Royal Family, Dr Nathaniel St Andre, whose qualifications were as a dancing master. Molyneux died shortly thereafter. |
