Peppermint Patty: What do you think love is, Chuck?
Charlie Brown: Well, years ago, my dad owned a black 1934 two-door sedan.
Peppermint Patty: What's that got to do with love?
Charlie Brown: Well, this is what he told me: there was this really cute girl, see? She used to go for rides with him in his car. And whenever he'd call for her, he would always hold open the car door for her. After she got in and he had closed the door, he'd walk around the back of the car to the driver's side, but before he could get there, she would reach over and press the button, locking him out. Then she'd just sit there and wrinkle her nose and grin at him. That's what I think love is.
