Motormouth Maybelle: [watching Edna walk in] If we get any more white people in here, this is gonna be a suburb.

Edna Turnblad: Imagine! My little girl... regular, at last.

Penny Pingleton: [after Tracy is rejected by Velma and the Council Members] I think they secretly liked you.

Penny Pingleton: [looks into the camera] I am now a checkerboard chick! [grabs Seaweed and kisses him passionately]

Edna Turnblad: Penny, get home before your mother shoots you.

[from trailer]
Link Larkin: [to Tracy] I think knowing you is the start of a pretty big adventure.

Penny Pingleton: Without that show I have nothing!
Prudy Pingleton: Having nothing builds character!

Penny Pingleton: Oh, no!
Tracy Turnblad: What?
Penny Pingleton: Your hair deflated!
Tracy Turnblad: Let it. It was just a symbol of my conformity to the man.
Penny Pingleton: You are so tough.

Prudy Pingleton: [tying Penny to her bed with a jump rope, as Penny stoically says nothing]
Prudy Pingleton: Penny Lou Pingleton, you are absolutely, positively, permanently punished. You will live on a diet of saltines and Tang, and you will never leave this room again.
Prudy Pingleton: [tosses holy water on Penny] Devil child, devil child!
Penny Pingleton: [glowers at her mother]

Mr. Spritzer: [about Tracy] I want that chubby Communist girl off my show!

Corny Collins: Tell me, Velma, how exactly do you fire Corny Collins from the Corny Collins show? [walks away]
Velma Von Tussle: [starts to speak and then pauses, frustrated] They do it all the time on "Lassie"!

Penny Pingleton: [about Amber] Plastic little spastic.

[from trailer]
Penny Pingleton: [to Tracy, at the dance] Get out there and show them!

[from trailer]
Corny Collins: [to Velma] You can fight it or you can rock out to it.

Velma Von Tussle: Incredible! I could do a fan dance with a lettuce leaf and you would remain completely obtuse!
Wilbur Turnblad: Obtuse?
Velma Von Tussle: Yes, obtuse!
Wilbur Turnblad: I flunked geometry...
Velma Von Tussle: ...yes, and biology too, no doubt!

Edna Turnblad: Well, I had a dream that I would own a coin-operated laundromat but I came down from that cloud real quickly!
