Kotaku:

Later this month, a very special Whopper is going on sale in Japan. Packed with five flame-grilled patties, this Whopper will be available only for a limited time.

The special Whopper goes on sale November 29 in Japan, which is “good meat day.“ It’s not a national holiday, but a pun. November 29 is 11-29. The eleven looks like the Japanese “ii" (いい), meaning “good.“ The numbers “2” and “9” are “ni" and “kyuu,“ which sounds like “niku" (肉), the Japanese word for “meat.“

I’m shocked that we in the States didn’t come up with “Good Meat Day" first.
