Calvin and Hobbes by Bill Watterson for February 09, 1988
Hobbes: How does this transmogrifier gun know what to transmogrify something into? Calvin: Telepathy. The gun automatically reads the brain waves you emit, and turns the object into whatever you want. Hobbes: That's amazing. Calvin: Well, it took me all morning to invent. Hobbes: So say I'm thinking about a big slab of grilled tuna now... Calvin: Watch were you're pointing that! Watch where you're pointing that!
