A: "Ugh. Here comes that evil old elf, the Trivial Case." B: "Aww. It looks friendly." A: "No! It's a false prophet that answers your question without providing the least shred of insight."
B: "Hey, are there any integers for which a⁴ + b⁴ = c⁴?" Elf: "Sure. a = b = c = 0."
B: "It's not wrong..." A: "I despise that creature. You don't have to be wrong to be the absolute worst."
