The School of Rock2003

Miss Mullins:
[about the teachers] They hate me.

Dewey Finn:
No they don't.

Miss Mullins:
Yes they do, I can see. I wasn't always like this, you know, I wasn't always wound this tight. There was a time where I was fun. I was funny! I was. But you can't be funny and be the principle of a prep school! No, you cannot. Because when it comes to their kids, these parents have no sense of humor. No. And if something goes wrong its my head in the smasher. And these parents will come down on me like a nucular bomb! I can't make a mistake! I gotta be perfect! And that pressure has turned me into something that I never wanted to be!

Miss Mullins:
[silently mouthing the words] A b*tch!

Dewey Finn:
No you're not.

Miss Mullins:
Yes I am. I am a big one!
