Hello. You might be wondering why I called you into my office. Let me show you.

This is the reason. We saw Teacher in the nude. Did you really? Was it you who wrote it?

You see, the reason you're here is I'm trying to find out who exactly wrote this on my blackboard.

Let me assure you, no one has seen Mrs Kane in the nude, or Miss, shall I say, until now.

You see, the joke is actually on you.
