Jimmy breaks a window at school with a slingshot...

...but the principal saw everything, and calls Jimmy in his office right away. Jimmy sits on the chair in front of the principal's desk.

"Jim, do you know why I called you here?"

"No sir."

"Don't you know who broke the window with a slingshot?"

"I don't understand, Sir."

"What don't you understand? It was a really simple question!"

"No, Sir, I don't understand literally! I can barely hear anything you say. Maybe it's the room's acoustics, or I dunno."

"Don't lie to me, Jim, that's nonsense!"

"I can show you, Sir! Come, sit in my place, and I go behind the desk. Let's see if you can hear what I say."

The principal skeptical at first, but eventually he agrees. So he sits down, and Jimmy sits in the principal's chair.

"Okay Jim, go ahead! Say something!"

"Sir, don't you know who was fucking the young teacher in the ladies' room after class yesterday?"

The principal shocked, he looks at Jim and says:

"You're right, Jim! There's something wrong with the room's acoustics..."
