Every Day is Right-Handers' Day

Are you ready? Today's the big day! International Left Handers' Day! Wheeeeee! How do you plan to celebrate? Is your costume ready for the parade? Are your out-of-town friends all coming? We heard that Bevan Dufty is going to ask every business in the city to file for bankruptcy in order to prevent rowdiness.

Friend of SFist Steve found the attached image in a bookstore window: apparently there's some store called "The Great Overland Book Company" that's offering 20% off on August 17, 18, and 19, but ONLY for left-handers. Well, okay -- now, when's the right-handers' day so the rest of the city can get a discount?
