Honestly, if you've never had one, you're dumb. Well not dumb, you just may not know any people who sell Girl Scout Cookies. Throw them in the refrigerator for a day or two and forget about them. It's a cool minty flavor, and it's worth the two day wait. Think Andes Mints on steroids. They're that good.
Word has it (according to a friend of mine I went to college with, James B.), there is an iPhone app for locating Girl Scout Cookies. I haven't downloaded it since I don't have an iPhone.
