The Facts of Life1979

[while the four girls work as waitresses in the cafeteria, snobbish Margo keeps teasing Jo. Jo does her best to ignore Margo]

Margo:
[to Molly] It's no surprise she's such a terrific waitress! I heard that's what her mother's been all her life.

[hearing that, Jo is about to beat the obnoxious girl]

Joanne 'Jo' Polniaczek:
You no good creep...!

[Blair stops Jo]

Blair Warner:
[smiling] Wait a minute, Jo. Don't stoop to her level. A situation like this calls for a rational, civilized behavior befitting a school like Eastland where dignity is our motto.

[Blair takes a leftover cream pie and smears it on Margo's face. Natalie and Tootie burst out laughing, but Jo is not content. Hearing the laughter, Mrs. Garret enters. As she sees what happened, she starts laughing too, but quickly gets hold of herself, while Margo tries to clean her face]
