A subterranean beast that resembles an old woman. They can be found in sewers, abandoned subway systems, and other dark, wet places. They hibernate every 20 years, then come out of their lair and apply for a job at the local middle or high school. These creatures love watching children suffer, and will regularly steal or "confiscate" the belongings of their students. Math teachers also have the unique ability to warp time and space, making their class period last longer than the others. Every couple of years a child will go missing at school and then a few months later they'll find the body in the sewer. There is still some speculation, but theorists suggest this was the teachers fault.

When a struggling sports team fires their coach, and a new coach comes in and the team initially does really well.
Everyone is all smiles, the new coach tries new things, is fun and upbeat, and seemingly *changes the culture* so the team performs really well.....until they don't.
The few good games are due to excitement, and once the substitute teacher has to be a real teacher, fails spectacularly because he actually has to teach.

Boris: Oh fuck, you see how the new coach has turned this team around. I told you the old guy sucked.
Edgar: Meh, it is the Substitute Teacher Effect, come back to me in 3 months. Team is just playing well. New guy can't coach.
3 months later.....
Edgar: Team sucks, and coach looks really constipated.
Boris: Ya, you were right. Substitute Teacher Effect wins again.
