A Very Odd Fish

I confound myself, I'm a very odd fish,
In that I do want I want and not what I wish,
And even when I wish and want the same thing,
It hooks my mouth tight and hangs me from string.
Don't listen to me, I don't know where I am,
Swimming the lake or hopping on land.
Are my scales shiny? Am I a good catch?
Will I be worth as much if my meat's not intact?
For the grill's hot and ready and coals are aflame,
You strip off my outsides along with my name,
But bare bones on fire aren't worth a whole lot,
You could throw me back but my carcass would rot,
So I'll sit here and ask what was it I did?
I may swim in circles but the worm told the fib.
You weren't even hungry, I could tell from your boat.
It was stained with grilled cheese and bananas afloat,
But I'm not a monkey, though I look to the trees,
And I'm no giraffe, though I look to the leaves,
And the sky soars on past them, but here I must lie,
Forced to watch idly as the clouds pass me by...
I know that I said I wanted out of this pond,
But the hook wasn't right and this air feels all wrong.
So braise me and broil me and fry me and bake,
There's really no telling how long it will take,
For as much as you try to make a succulent dish,
I feel I must warn you, I'm a very odd fish.
