Pipe smoking leprechauns; four leaf clovers; green beer; corned beef and cabbage, shortening o' prepositions, as in Luck o' the Irish...
There are many good reasons for drinking,
One has just entered my head,
If a man doesn't drink when he's living,
How the hell can he drink when he's dead?
"May you always have a clean shirt,
a clear conscience, and enough
coins in your pocket to buy a pint!"
