Unfortunately weirdo-foodies, if you wanna try this you'll have to hitch it to Japan.
Burger King is introducing it's limited-time Pumpkin Burger in Japan. It consists of a beef patty, bacon, lettuce, two pieces of fried Japanese pumpkin, and a special sauce (made from a whole bunch of different nuts).
The burger will cost somewhere between $4 and $7 American... plus your round-trip ticket to Japan, which I just found for you on Kayak.com for $861. What a steal!!!
Pumpkin burger here you come! Go get it!!
