What will be the teacher's first word in class?

This market will resolve to the first word the teacher says out loud to the class once the lesson begins. Greetings to individual students in the corridor, mumbling to themselves, and words said before the door closes do not count.

If the first word is not one of the listed outcomes, or the lesson is cancelled, all outcomes resolve to "No". Filler noises ("erm", "uh") are ignored. "You lot" counts as a single outcome if both words are said together.
