Happy St. Patrick's Day!

Yes, it's the day for the "wearin' of the green"... but, are you Irish??  When I was a little guy, my Grandma (half Irish) used to say that if you're Irish and you don't wear green on St. Patty's Day, you get pinched.  And, if you're not Irish and you wear green, you also get pinched.  Does anyone else remember that practice?
