Confirming our belief that Japan is at once among the coolest and craziest places on this planet we all call home is Burger King's exclusive Windows 7 Whopper. Seven stacked beef patties extend your usual Whopper to over five inches in height and the whole thing costs an appropriate ¥777 (or $8.55). It'll be available for one week only -- or seven days, get it? Join us past the break to see the full towering size of this meaty monstrosity.
Update: Andy Yang, our Engadget Chinese editor, has read the smallprint and noted that in fact only the first 30 customers each day will get the Win 7 Whopper at ¥777, with the rest shelling out a cool ¥1,450 ($17.10) for the privilege. Way to break with the number 7 theme, guys.
