What is the funniest thing that a student has said to you in the classroom, either wittingly or unwittingly?

When a student tried to teanslate a proverb from his mother tongue to English . It did not make any sense but it was very fun!

When doing one on one lessons and the student looks behind himself for someone to answer the question.

It was when one of my students amswered my question which was '' tell me two pronouns'' he was not following and he said: who ? me? and i said '' yes true ,very good.
