Ash: "You really like my backpack, don't you?"

Nebby: "You fool. You absolute f**king FOOL. You would willingly confine yourself within that mobile prison? Though he called it a ''backpack'', it is just another form of bag, the root of all evil in this universe. To place yourself within the confides of such a dastardly contraption only proves to me that you have far too much to learn about the ways of the world. Once you enter that bag, there is no going back. You'll be forced back inside that h**lish place again, and again, and AGAIN no matter how many times you daringly escape. I will not allow this act to go unscolded. Pew to you, good sir."
