It's Talk Like a Pirate Day!
According to Summers, the day is the only known holiday to come into being as a result of a sports injury. During a racquetball game between Summers and Baur, one of them reacted to the pain with an outburst of "Aaarrr!", and the idea was born. That game took place on June 6, 1995, but out of respect for the observance of the Normandy landings, they chose Summers' ex-wife's birthday, as it would be easy for him to remember.
At first an inside joke between two friends, the holiday gained exposure when Baur and Summers sent a letter about their invented holiday to the American syndicated humor columnist Dave Barry in 2002. Barry liked the idea and promoted the day, and later appeared in a cameo in their "Drunken Sailor" Sing Along A-Go-Go video. Growing media coverage of the holiday after Barry's column has ensured that this event is now celebrated internationally, and Baur and Summers now sell books and T-shirts related to the theme on their website. Part of the success for the international spread of the holiday has been attributed to non-restriction of the idea or non-trademarking, in effect opening the holiday to creativity and "viral" growth.
The association of pirates with peglegs, parrots, and treasure maps, popularized in Robert Louis Stevenson's novel Treasure Island (1883), has had a significant influence on parody pirate culture. Talk Like a Pirate Day is celebrated with hidden easter egg features in many games and websites, with Facebook introducing a pirate-translated version of its website on Talk Like a Pirate Day 2008 and publisher O'Reilly discounting books on the R programming language to celebrate. In September 2014, Reddit added a pirate theme to their website.
