Yes, but in the opposite direction of everyone else.
First, I am part Irish, but I don’t really celebrate it, or most of my heritages. I am a genealogist, and recognize the large number of groups in my background (Irish, Scottish, German, English, Bohemian), but I really only call myself an American.
Second, I work for the phone company as a cable splicer.
Years ago, I had to go into a splice that was worked on 5 years earlier by an Irishman. He bragged about what he had done at the yard, so I know he did this.
I guess you should know that some telephone cables have color coding on the wires. There are 25 pairs of wires, all color coded, and bundled in groups with more color coding. You know that the first pair of the seventh group is pair 151, and is a blue-white pair in the Red-Orange group.
Well, the above mentioned Irishman had a few too many before working, and decided that, it being St. Patricks day and all, he would change the group markers to all green. The result is being unable to decode which group has which wires. I spent a day or two undoing his work, before I could perform my own work.
So, I celebrate St. Patrick’s day as Splicer Appreciation day.
