A: “2 + 2 = 5, therefore you should brush your teeth.”
B: “Two plus two doesn't equal five.”
A: “Why you don't want to brush your teeth?”
B: “I do, but not because two plus two equals five, since it doesn't!”
A: “You have to brush your teeth because two plus two equals five!”
B: “I won't!”
A: “You won't brush your teeth?”
B: “I will, but not because 2 + 2 = 5.”
(B brushes her teeth)
A: Hah! You brushed your teeth! So you agree that 2 + 2 = 5!
Inspired by discussions with my boss.
