The most interesting teachers at my school are one of the RE teachers/school chaplain and the Japanese teacher. Pretty much all the students think the RE teacher is a bit of a paedophile, he apparently tries to look up girls skirts and is just a bit odd. The Japanese teacher is a guy in his thirties who has a little shrine to Hello Kitty (lots of pink hello kitty stuff) on the mantlepiece in his classroom.
My form tutor also has a habit of wearing shortish skirts and sitting on the desks; she's past 50. It really freaks the boys out.
And I won't even go into the complicated mess that involves two of the teachers now shacking up together.
