Suspension jokes

The teacher of the ELA class said that whoever answers this next question gets to go home. Then a kid sitting next to the window threw his bag out the window. 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.

How do you leave an idiot in suspense? I'll tell you tomorrow!
