Mark Steyn calls Mayor Bloomberg a “loathsome slug of a man” for slandering a tourist who was unaware that New York City routinely defies the Second Amendment, by alleging falsely that the white powder she had in her pocket was cocaine when tests had already shown it was what she said it was, powdered aspirin.

InstaPundit agrees: “Loathsome slug is right.”

At first I thought they were being unfair to slugs, who do, after all, fill a useful niche in the ecosystem. At least, I assume they do, though I’m not sure what precise role they play besides providing food for unfastidious predators. On second thought, I realized that “slug” is a more appropriate epithet than Steyn or Reynolds seem to notice. Is it a coincidence that Mayor Bloomberg is vehemently opposed to salt, and deeply suspicious of other harmless white powders like aspirin? Harmless to others, I should say: perhaps that Englishman who thinks the world is ruled by shape-shifting lizards from outer space is almost, but not quite, right, and they’re actually shape-shifting slugs. (Try saying that three times fast.) The only way to be sure is for some brave person to spill some salt on him. If he’s (technically) human, it wouldn’t hurt him, and if he’s a shape-shifting alien slug it wouldn’t really be murder, would it?
