A funny story

Yesterday, I told one of my classes we'd be having a visitor to take care of some administrative things. Of course, they wanted to know who it'd be, but I refused to tell them. Here's how it went:

MrT: You'll have to wait and see.
Student: Is it Bossman?
MrT: No. Worse.
Student: Is it Bosswoman?
MrT: No. Worse.
Student: Is it both BM and BW
MrT: No. Even worse.

There was a knock on the door 10 minutes later, Young Secretary came in and the students burst out laughing. One looked at me and said, 'You were right!'
