We say things that make one wonder how it all began. For instance, bite the bullet: the bullet is too hard to bite into, and who in the right mind would want to bite the bullet? Suppose I am crazy and I bite the bullet and I bite too hard and the bullet explodes in my mouth? ... here is another one: shoot: shoot who? You? Me? The dog? Makes no sense at all to shoot anyone or anything. And why? ... a million ways to skin the cat: which cat? Mine or yours? I don't like to skin cats. We don't eat cats to skin them. Do you kill the cat first, and then you skin it? Or do you skin it alive? No matter how you dice it (wait ... dice what, the tomatoes? ) It sounds cruel to me. Or, this one, she's a ham. Wait a minute, I thought she was a person not a meat cut.
