Fingers
The first one is opposable, and therefore is quite utile,
Though given its utility, its name sounds pretty dumb.
Without it, many tools and toys would all be rendered futile,
And every hitchhiker agrees: it's great to have a thumb.
The second one is also an important thing to own.
It helps you daily to do almost anything you please.
It's good for pointing, poking, crooking, dialing telephones,
And I am told it's also great for reading indices.
Then we move on to number 3, the middle one, the bird,
The longest of them all, but not too useful by itself
...Unless you wish to digitally signal the F-word
(An action best accomplished with a modicum of stealth).
What's next, the fourth one in the set, is harder to control.
You have to use its neighbors too, or it can't do a thing,
Except for maybe scraping chocolate icing from a bowl,
While some folks think that it's the best place to display a ring.
The last one, number five, may seem quite puny, I confess.
But still, it holds its own against the others, pound for pound:
It's maybe even the most crucial digit you possess,
Because, dear Sarah, it's the one you've got ME wrapped around!
