Marc at Bad Catholic:
"If you find yourself drenched in lemonade, but know that you haven't drenched yourself, what is left to conclude? That someone else has drenched you. If you find yourself drenched in worth, but know that you have no reason to feel worth, what is left to conclude? That someone has given you worth. It's a joke, see, because you're drenched in lemonade, and worth everything! Who among you would find themselves drenched in lemonade, look around and realize they could not have drenched themselves, and thus concluded that they were not, in fact, ever drenched."
