2 + 2 = 5

Founding father and President of the United States John Adams wrote sometime around 1794 that “Human understanding is its own revelation, and has made it certain that two and one makes three; and that one is not three; nor can three be one. Miracles or prophecies might frighten us out of our wits; might scare us to death; might induce us to lie; to say that 2 and 2 make 5. But we should not believe it. We should know the contrary.”

Sometimes 2 + 2 = 5
