A young teacher is teaching vocabulary to her first grade class. She draws an apple on the blackboard and asks, ""can anyone tell me what this is?"" ""That's an ass."" says a student in the back. ""No..."" ""That's definitely an ass."" says another student. After a few similar exchanges the frustrated teacher starts to cry. The principal walks by the classroom and notices the sobbing teacher, walks in, and immediately understood what was going on. ""You rascals!"" he yells, ""I want whoever drew this ass on the board to come forward this INSTANT!""
