A pizza burger? Only an American could come up with that one.
You guys were the ones to come up with hot dog stuffed crust pizza.

Though it's no help that BK released this at about the same time.

It turns out the pizza burger that I linked to is different from the one I posted a picture of. The main difference you'll notice between the two of them is the one in the article has one giant patty as opposed to several patties on one bun.
Is there any doubt at all that an American came up with this idea?
Yes, as a matter of fact, there is. Ironically enough, the one I posted a picture of is not available in the United States. The 6-patty burger is only available in Dubai.
There's no way it could have become a popular menu item!
6 burgers for the price of... fewer than that many. I can easily see people in Dubai jumping up and down at that reasonable deal.
As for the New York one, I haven't seen anything that would indicate that it's still in existence.
Let's call it the "Pizzer" then! ;)
Excuse me while I go take a pizzer.
No, that name wouldn't work.
I'm average weight, but I can eat 5 McD burgers easily... and they are just snack sized too!
Those patties were BK-sized. Mickey D's makes tiny burgers.
And if you haven't had enough of this madness, here's the inevitable double decker pizza burger.
Good thing those green beans are there to keep it healthy.
