September 18 is National Cheeseburger Day! Why? I don't know; National Burger Month was back in May, and National Burger Day was on May 28. You can celebrate by going out for an awesome burger or making an awesome burger (perhaps grilling an awesome burger?), but of course, we'd recommend doing any of those things on any day of the year.
