Men of the world, prepare to squirm like you've never squirmed before.
According to the student who filmed this, both people involved were teachers and it was his AP Physics teacher lying on the floor who ended up taking the blunt end of an axe to the crotch as this physics demonstration went awry. We're not sure what demo requires lying on the floor with a cinder block on your chest and getting hit with an axe, but thankfully the teacher was fine (if "walked funny for like a couple of days" qualifies as fine) and only grazed his crotch and wasn't "a full on partitioning".
