Quotes

Daphne Blake: Velma, here's the only thing you ever need to know about boys. They are stupid. If you give a boy two choices, a smart one and a stupid one, he will always make the stupid one every time. That's why you never give them a choice.
Velma Dinkley: That's depressing.
Daphne Blake: Yes, it is.
