You Think Julia Child Might've Mentioned It

Want to know what JUST occurred to me?

On November 15, 2007 it JUST occurred to me that you could use another type of cheese other than American in a grilled cheese sandwich. Seriously. THAT just occurred to me. I'm 31 years old. WHY would I never thought of that? Heard of that?

These are the things that cross my mind.

Things that cross Copernicus' mind were, oh I dunno, realizing the planets revolved around the sun and not around the Earth.

I feel so small and insignificant right now. All thanks to a hot oozy grilled cheese sandwich. Oh well.

Which cheese would you use??
