Bolster our fitness, O Lord, and for these individuals of lower tropic levels, which we shall consume to maintain our fitness, we thank you. Through Darwin our prophet and evolutionary biology, Amen.
God may exist, or God may not exist, but as a self-aware species we are grateful for our highly evolved consciousness nonetheless. If there is an invisible, all-powerful deity, we thank him for our food, drink, comfort, and not putting our noses on our backsides as a practical joke.
For single, lonely comic book nerds:
Our lord Superman, son of Jor-El, we thank you for the (relative) peace on Earth. For defending us from Braniac and Darkseid, for keeping the capitalist takeover of Wall Street by Lex Luthor in check, and for using your jealousy-inspiring powers for good. But most of all, for those we love, unless we’re talking about Lois Lane, who was totally into us in college, but then you had to come on the scene, with all your powers, showing off and totally cockblocking us, you total jerk. Just kidding. Please don’t burn us with your not-at-all-overpowered laser vision.
For a family fallen on hard times:
O Lord, we thank you for the gifts of your bounty which we enjoy at this table, even though most of it is generic label. As you have provided for us in the past, so may you continue to sustain us, even if we have to stop eating out and start teaching our kids to enjoy Ramen for every meal. We know you will not forget the needy, which kind of includes us at the moment, ever since John lost his job and Sarah and Joey have had to start taking the bus and bringing bagged lunches instead of buying them at school. We know that your love is infinite, and maybe if some of that could take the form of a shower of gold, it would be greatly appreciated.
For after a recent breakup:
Our God, who both gives and takes away that perfect angel Lana, with her golden hair and most beautiful face ever, please bless this meal, even though everything tastes like dust without her. Please, O Lord, grant us peace and serenity in our coming days, and take away these feelings that I want to curl up and eat ice cream for the rest of my life.
