Question

I was out the other day, replacing my cell phone, (didn't get ANYTHING nearly as cool as Cami did, but I like it, that is the one I got, in the picture) and the young woman helping me was enjoying an afternoon snack.
It's all good, she put it away when I got there and didn't sit there, eating while she was assisting me. She was very nice. The snack, though, was Grape Nuts.
This prompted a discussion throughout the store (it was a slow, rainy afternoon) about why the hell those things are called Grape Nuts?
I told them I would submit the question to you, my few, but smart, blog readers, and friends.
So, here is a weekend question. Don't google it, that takes away all the fun. (Though I imagine at some point I might).
Why are Grape Nuts called Grape Nuts?
Anyone?

Oh, and I got to download ringtones for each person in my address book. I had waaaay too much fun picking things. . .
