Since the world is so uncertain, it's nice to know you can count on some things.
Like your fingers.
And if you take off your shoes, you can count on your toes.
You've heard the expression, "I wouldn't give an arm or a leg for it."
Well, would you give a hand or a foot for it?
How about a finger or a toe for it?
Maybe you'd give a little toe, because it's like the appendix. You don't it to live.
But if you do that, you must remember that you can't count on that toe any more.
Or surely you'd might give a fingernail or a toenail for it.
