I might be a bit late to the party but here's my story:

In fourth grade, I had a teacher who was a little person and was prone to fits of rage. She'd broken projectors, clipboards, dozens of pencils, you name it over the smallest things. One day, however, she ended up breaking something much more valuable (at least to us students) than anything she'd broken before.

We had a class hamster (don't remember the name, there were a few that year but that's a story for another time) that was meant to teach responsibility (different students took it home on the weekends) and basically just help to keep everyone in a good mood. One day she was talking from the front of the class while holding the hamster with one hand and petting it with the other. Something, probably a student misbehaving, set her off and she starts arguing with the student. The hand that she's been petting the hamster with is now pointing at and being used to gesture at the misbehaving student. She finally bellows out "I'm... getting... FURIOUS!" which is pretty much an indicator of when shit hits the fan with her. [[side note: I wish I could remember more about the scenario just so I could relay it better to you but it's been years since it's happened and me trying to scrub it from my memory is interfering with that]] Her face begins to get red from screaming while the girls in the front row of desks begin pleading "Mrs. xxx you're hurting her!" The argument continues for about a minute more at which point the teacher has a chance to calm down and realize what she'd done. I wasn't actually an eyewitness to the squeezing itself (back of the class and squeamish so I tried to look away) but, in the midst of her argument, the teacher managed to squeeze a whole lot more than the life out of the poor hamster. The aftermath was pretty much blood coming from both ends, eyes popped out of their sockets, and I didn't want to stick around to find out what else she squeezed from that poor rodent.

Oh, and that teacher still teaches at the same elementary school.

Sorry in advance for any grammatical or spelling mistakes!
