Something

There it lays upon the chair
Mysterious how it just sits there.
Not a movement, for it can't
Not a sound, for it shan't.
If it fell, might it break?
How much torture could it take?
If it rolled where would it go?
If it's sharp, could it sew?
If it's empty, could you fill?
When it's working, is it still?
If you smelled, would it scent?
Is it worth the money spent?
As you see, it's undefined...
Cause I'm just messin' with your mind!
