crumbs anyone?

I made 3 dozen muffins figuring we'd eat a dozen for breakfast and the rest could go into the freezer for another day. I took the first 24 out of the oven and set them on the counter to cool while the last 12 went in to bake. When I came back to take out that last batch, all that was left was a neat little stack of empty papers and a few crumbs. . .
