Once-ler: At first I didn't realize
 I needed all this stuff,
 I had a little cottage,
 And that cottage was enough.

 place where I could sit and knit,
 place where I could sell my Thneeds,
 But now I've had a little time
 To re-assess my needs.

 And I need a bigger office,
 I need a bigger chair.
 bigger desk, a bigger staff,
 bigger hat to wear.

 Because I'm biggering,
 I'm figuring on biggering,
 And biggering is triggering
 More biggering. 

 Lorax: Now listen up, meathead. 
 I'm going to say this once, and I'm not gonna repeat it.
 Greed...it's like a little pet, alright?
 And the more and more you feed it,
 The more hungry it'll get!
 But...no, you can't really blame greed
 No, that's stupid.
 You see, it's gotta word inside.
 Yeah, that's right.
 It's one that always needs to feed,
 And it's never satisfied. 
 You get it?
 And the more you try to find it,
 The more it likes to hide. Okay?
 Now listen--that is NASTY little word.
 And I like to call it "pride."
 Now that's why you're biggering!
 Listen here, idiot! 
 I"m sick of all your biggering!
 Because all that biggering is triggering more biggering!
 Got that? Alright!

 Once-ler: There is a principle of nature,
 That most every creature knows.
 It's called survival of the [bad word] 
 Yeah and this is how it goes.
 The animal that wins has got to
 Kick and claw and bite and punch.
 And the animal that doesn't, well
 They wind up someone else's lunch.

 [bad word] s an animal,
 That's trying to survive.
 [bad word]  and fighting,
 Just to keep herself alive.
 And that's why I'm biggering,
 I"m figuring on biggering,
 And all this biggering is triggering
 More biggering.

 I won't stop!
 Biggering,
 I'm biggering and biggering,
 And biggering is triggering more biggering.
 And the customers are buying,
 And the money's multiplying 
 And the people are all lying 
 And the lawyers are denying,
 Who cares if the trees are dying?
I don't wanna hear your crying!
This is all so gratifying...
 I'll just keep biggering.
