You're in Love, Charlie Brown (1967 TV Movie)
Charlie Brown: It's stupid to just sit here and admire that little red haired girl from a distance. It's stupid not to get up and go over and talk to her.
Charlie Brown: It's really stupid! It's just plain stupid; so why I don't I go over and talk to her?
Charlie Brown: Because I'm stupid.
[unable to face the Little Red-Haired Girl, Charlie Brown covers his face up in his lunch bag, and rushes for the entry line when the bell rings. Blinded, he bumps into Lucy]
Lucy van Pelt: Good grief, Charlie Brown! You're ridiculous!
Charlie Brown: I can't help it, Lucy! I just can't face the Little Red-Haired Girl... Pretty faces make me nervous.
Lucy van Pelt: How come *my* face doesn't make you nervous?
[as Charlie Brown walks off, with Lucy following him]
Lucy van Pelt: I've noticed you can talk to *me*! *I* have a pretty face! So how come you can talk to me? Wasn't I the Christmas Queen? You haven't answered!
Charlie Brown: There's nothing like unrequited love to take all the flavor out of a peanut butter sandwich.
Charlie Brown: [running after the bus after he wakes up at the bus stop] Hey! You there! Bus! Stop! Hey, bus! Stop, bus!
Lucy van Pelt, Violet: [singing, teasing Charlie Brown] Poor little Charlie Brown, nyah, nyah, nyah! No one could love that frown, nyah, nyah, nyah! Who would love you? No one, that's who! Your face is too darn round, nyah, nyah, nyah! Your face is too darn round!
