I've talked about this in previous years. My Human grew up in this stupid town called Rolla, Missouri. St. Pat's is the most important holiday there. It has to do with St. Patrick being called the Patron Saint of Engineers. Rolla has this university that teaches humans to drink large quantities of alcohol and to become Engineers. These are not the type of Engineers that drive trains around, though. You don't want those Engineers to be drunk. But apparently it is okay to be a drunken other type of Engineer.
Each year in Rolla there is a big parade and festivities. One thing happens every year in Rolla that every dog can appreciate: They paint the main street (called Pine Street, because humans are stupid) green with a substance called Alice. What is in Alice, you might ask. Oh, just about everything you can imagine, including stuff that comes out of humans when they have consumed too much alcohol. The prestigious Knights of St Pat are the ones who are in charge of Alice. In the good old days new Knights were tossed into Alice as a part of their Knighting ceremony. It was a big honor. (Think about the smell!) But in the 1990's, the administration of the university decided that it was too much of a liability to have humans put in the goo.
It has been a tradition for many years that humans can buy St. Pat's sweatshirts (and other products). I've featured their designs the past 2 years. This year is no exception:
