From The Lorax
[reacting to the Once-ler making a "thneed" from a tree he cut down
I am the Lorax. I speak for the trees. I speak for the trees, for the trees have no tongues. And I'm asking you sir, at the top of my lungs - that thing! That horrible thing that I see! What's that thing you've made out of my truffula tree?
Look, Lorax, calm down. There's no cause for alarm. I chopped just one tree, I'm doing no harm. This thing is most useful! This thing is a "thneed." A theed, a fine something-that-all-people-need! It's a shirt. It's a sock. It's a glove! It's a hat! But it has other uses, yes, far beyond that. You can use it for carpets, for pillows, for sheets, for curtains! Or covers for bicycle seats!
