From Charlie and the Chocolate Factory

"Willy Wonka: Do you like my meadow? Try some of my grass! Please have a blade, please do, it's so delectable and so darn good looking!

Charlie Bucket: You can eat the grass?

Willy Wonka: Of course you can! Everything in this room is eatable, even *I'm* eatable! But that is called "cannibalism," my dear children, and is in fact frowned upon in most societies."
