Dr. Seuss Explains Leverage

I have a dolly on my shelf
And I sewed it all by myself!
I used new needles and red thread,
And hair I ripped out of your head,
With your old shirt, button eyes and glue.
Don’t you think it looks like you?

All I need now are big black pins;
Now which part should I stick them in?
In dolly’s heart?  In dolly’s eyes?
I think I’ll leave that a surprise.
So next time I tell you a secret
I know you’ll be sure to keep it.
