If that guy at the office - you know who we mean - keeps saying things like "Arrrr," and "Shiver me timbers!" don't be too alarmed. It's because today is International Talk Like a Pirate Day, an unofficial holiday that celebrates all things pirate.
The holiday was created in 1995 by John Baur ("Cap'n Slappy") and Mark Summers ("Ol' Chumbucket") of Albany, Oregon.
According to Wikipedia, the idea came to Baur and Summers during a racquetball game when one of them reacted to an injury with an outburst of "Aaaarrr!" That game took place on June 6, 1995, but out of respect for the observance of D-Day, they chose Summers' ex-wife's birthday, Sept. 19.

The holiday gained widespread attention when they sent a letter about their invented holiday to Miami Herald columnist Dave Barry in 2002. Barry liked the idea and promoted the day.
Today the "holiday" is celebrated internationally, with parties and parades.
And perhaps it's gaining some legitimacy. Michigan and California have officially recognized the day, according to WIkipedia.
