Well, I quoted Scotchtoberfest due to people creating a REAL holiday out of the fictional one that was aired on the Simpsons.... since then, people have turned it into another Scottish-themed holiday, usually involving imbibing in many a glass of Scotch.

Third Friday of October is the day.... in addition to Tartan Day, St. Andrew's Day, Robbie Burns Day, Orange Day if you're of Protestant descent....
