The great logician¹ Betrand Russell once claimed that he could prove anything if given that 1+1=1.

伟大的逻辑学家罗素曾说过用1+1=1他可以证明一切事物。

So one day , some smarty一pants asked him; "0k. Prove that you're the Pope.”

一天，几个自作聪明的人问他:“证明一下你是教皇。”

He thought for a while and proclaimed, "I am one. The Pope is one. Therefore, the Pope and I are one.”

他想了想，然后说“我是一个人，教皇是一个人，所以我们都是一个人。”
