Public drunkenness on Patrick’s Day isn’t a new thingFor all the hand-wringing about how terrible it may be, people have been getting drunk on Patrick’s Day for a long time. This New York Times report from 19 March 1860 jumps straight in, noting that “there were a great many persons very much intoxicated” at the city’s parade. It also contains one of the best descriptions of the phases of drunkenness that we’ve ever read, where the writer describes seeing:…officers waiting on men and women in all stages of intoxication, from that balmy condition in which a man swears eternal friendship to all the world, and is anxious to embrace everyone he meets, to that in which he is unable to walk without tying knots in his legs, though supported by an official friend on either side.

No, there were no snakes in Ireland. Patrick’s writings don’t contain any references at all to snakes – or to shamrocks, for that matter.

The world’s largest shamrock is in NebraskaThe town of O’Neill (“Nebraska’s Irish capital”, apparently) started drawing a giant shamrock on its motorway every year for Patrick’s Day in the 1980s.

JFK once forgot about Patrick’s Day while he was president. Awkward.John F Kennedy had a lot on his plate in the first 100 days after his inauguration as US president in 1961 – so maybe that’s why he forgot about Patrick’s Day until Ireland’s ambassador to the US, Thomas Kiernan, turned up at the White House with a bowl of shamrock on 17 March. His staff apparently had to dig up a green tie for the president for the photographs.
