Nope. Not an Onion headline. 

It's official, Burger King Japan might be the most experimental of all the Burger Kings. After the pumpkin burger, the black bun burgers and five-patty Whoppers, the chain has set a high bar for novelty. For its next trick, in honor of its fifth anniversary, Burger King Japan is offering an all-you-can-eat burger buffet.

This gorge-fest does have a time limit, though, and a short one at that. Customers only have a half hour to cram as many hamburgers, fries or onion rings as possible into their mouths.

The special runs from November 17 until November 21 for black burgers and from November 22 until November 30 for Whoppers.

Again, this sounds like a great word-of-mouth campaign to reach the untapped market that is Japanese emergency rooms.
