I guess nowadays you could get suspended for singing:
“My eyes have seen the glory of the burning of the school,
we have tortured every teacher, we have broken every rule,
We blew up the library and the cafeteria too
And our troops go marching on!”
Glory Glory Hallelujah
Teacher hit me with a ruler
Shot her with a .44
and she fell to the floor
and she ain’t our teacher no more.
