Are you there God? It's me, hungry

I just passed a couple eating lunch outdoors at the sidewalk cafe near my office. Their heads were down in silence, and at first I thought they were examining their pizza for something (hairs, dirt, who knows). Then I realized they were praying. Oh. My bad. I don't suppose their grace went anything like this:

We thank thee father for the many blessings you have bestowed upon us today, especially the extra cheese on this here slice of pizza. Bless us, o Lord, with your gift to make the calories not count. Give us the strength to order the salad next time.

No, me neither.
