back in 9th grade i had this bat stuff insane FoT teacher who would throw our hall-pass (which happened to be a block of wood) at the walls, doors, desks, etc.
he broke several chairs and desks and one computer but he always blamed it on students
would constantly threaten to kill himself and other students with a hammer
had random bursts of cussing and screaming followed babbling
finally got fired after threatening to rape a kid because he wouldnt shut up while the teacher was talking
everyone forgot about him since then
