Yup this!

But what shocked me was that between the top bun and the middle bun there was nothing. Bone dry bread on bread. I've never dissected a big mac before, is it just dry meat between the two top breads?

The sad thing is I ate this monstrosity, just tossed the top bun away. Saddest meal of my life that I can recall.... and now that I've typed that out, I can look on the other side and be thankful to have had that whereas others have less.
