A mathematician¹ wanders back home at 3a.m. and proceeds to get an earful from his wife.

“You’re late!” she yells. “You said you’d be home by 11:45!”

“Actually,” the mathematician replies coolly, “I said I’d be home by a quarter of 12.”

一个数学家在晚上3点时徘徊着回家，结果被老婆骂了一顿。

“你特么怎么这么晚！”她大喊道：“你说你会11点45分前回来的！”

“事实上……”这位数学家蛋定地回复到：“我说的是在‘12的四分之一’也就是3点回来”

Hint：a quarter是四分之一的意思，目测数学家今晚要跪搓衣板。
