Ruler's End

The joke plays on the double meaning of "at the end of the ruler". The teacher implies the idiot is figuratively at the end, but the student pretends the idiot is literally at one of the two physical ends of the ruler, implying the teacher might be the idiot.

Teacher asked who threw that, he said, "Me, I'm going home." Before he could move the teacher pointed a ruler at him and said, "At the end of this ruler is an idiot," he got suspended for asking which end.
