If an experienced teacher started work at Hogwarts: Part 2

 Professor Dumbledore: Quidditch is cancelled this year.

Professor A.Teacher: Quidditch?

Professor Dumbedore: We let 14 of the students attack each other in the air while balancing on narrow strips of wood.

A.Teacher: What? Is that safe????

Dumbledore: .... No-one's died recently.

A.Teacher: Recently? Has anyone been injured?

Dumbledore: Yes, but we've always been able to fix them up.

A.Teacher: Oh. Nothing too major then?

Dumbledore: well... someone fell out of the sky last year when some evil monsters attacked the school. And that same kid also had his arm broken the year before. Also he nearly choked on one of the balls in his first game. But besides that one kid, there's only been a few maimings.

A.Teacher: .... Wow. Sounds like it's being cancelled is a good thing.

Dumbledore: Yes! It will let us host the Triwizard tournament!

A.Teacher: What's that?

Dumbledore: It's where we put three students in challenging situations to test their resolve, magical skill and ingenuity.

A.Teacher: Well, that sounds a lot better! What kind of situation would this be?

Dumbledore: Well, there's a dragon...

A.Teacher: Nope.
