One Bite

"Queen: And since you've been so good to poor old Granny, I'll share a secret with you. This is no ordinary apple. It's a magic wishing apple.
Snow White: A wishing apple?
Queen: Yes. One bite, and all your dreams will come true.
Snow White: Really?
Queen: Yes, girlie. Now, make a wish, and take a bite." (Snow White and the Seven Dwarfs, 1937)
