Saint Patrick. Drove evil out of Ireland. Irish (well, he went to Ireland and lived there).
A merry St. Patrick's Day to you, gentlemen. Be good. Drink some Guinness. Or Harp. I'll be drinking one of each. St. Patrick, may all we men be true gentlemen.
(Could this here post be any more filled with short, choppy sentences? Probably. So I'll stop here, and raise my glass to ye. Cheers!)
Post Script: Don't forget to play the song at the right top side o' the page.
