Here are 10 interesting facts and pieces of trivia about St. Patrick's Day.

1.) Saint Patrick wasn't Irish. He was actually born in Scotland or Wales. His given name was Maewyn. He only ended up in Ireland because he was brought there as a slave. He did die on March 17th though. You might want to pour out a little in his honor (although, on this day, that could get you killed.)

2.) There are only three places in the world where St. Patrick's Day is a public holiday. Ireland. (Logically). The Canadian province of Newfoundland and Labrador. (Hmm...) And the Caribbean island of Montserrat. (Wait... what?)

3.) In Ireland, bars were closed on St. Patrick's Day... until 1970. In 1903, James O'Mara, a member of the Irish parliament, introduced an act that made St. Patrick's Day a national holiday. And while that was cool... by law, that meant that bars had to be closed on that day. And they were, until that law was overturned in 1970.

4.) There are nine times more Americans with Irish ancestry than residents in Ireland. More than 35 million Americans have Irish ancestry; the population of Ireland is 4.2 million. Irish is actually the second-most common ancestry in the U.S., behind German. (But don't sleep on Mexican. It's creepin' up on you. For our children, Cinco de Mayo is going to be the new St. Patrick's Day.)

5.) St. Patrick's Day is called the "Super Bowl of keg theft." Bars go through kegs and kegs of beer today, and generally stash the kegs out back to make room for people in their bars. That, according to Andrew Mullen, a bar owner in Kansas City, Missouri, makes today the "Super Bowl of keg theft." Scrap metal prices are good... everyone's poor... and at about $20 for an empty keg, some thieves really take advantage of today to cash in.

6.) St. Patrick's Day Isn't the Most Popular Holiday for Drinking.  In fact, it wasn't even in the top three.  In a recent survey, St. Patrick's Day came in fourth, behind New Year's Eve, Christmas, and the Fourth of July.

7.) Four out of five Americans wear green on St. Patrick's Day. That's about 240 million, which seems exceptionally high. About 34 million plan to cook or eat something special today. About 20 million plan to go out to a bar.

8.) St. Patrick's favorite color was blue. Not sure how anyone knows this.

Evil has a whole new rap!

9.) There have been six "Leprechaun" movies. Six. All six have starred Warwick Davis. And they are...

"Leprechaun" (1993) - Co-starring a pre-"Friends" Jennifer Aniston.

"Leprechaun 2" (1994)

"Leprechaun 3" (1995) - This one started the straight-to-video trend.

"Leprechaun 4: In Space" (1997) - Because Earth couldn't hold the leprechaun any longer.
"Leprechaun in the Hood" (2000) - Co-starring Ice-T.
"Leprechaun: Back 2 tha Hood" (2003)

10.) St. Patrick's Day is the eighth-largest card-sending holiday in the U.S. About 10 million people give out cards for St. Patrick's Day. That ranks behind, in order, Christmas, Valentine's Day, Mother's Day, Father's Day, Easter, Halloween and Thanksgiving.
