What's your favoirite brand/flavor of potato chip? Dating back to the 1850's, it's America's favorite snack - to the tune of 15 billion dollars a year. My personal favs include BBQ and Vinegar and Sea Salt.
For the more intellectual amongst us it's also National PI Day, as in 3.14. Many ways to celebrate this including eating pizza or some sweet type of pie. Sounds better than calculating pi out to several thousand places..
