Detention for anal retention

My son is the number one fan for Dr John and has an assignment to write a piece of music, so I suggested that he change the lyrics to one of his songs to comment on how kids won't crap at school: 

Oh my
L33T0N High 
taught me to crap
in my own time

Their bathroom stalls
don't have doors
unless you like gaping with kids vaping
then you'll never cross that tiled floor

I wouldn't be in the shit if I could have shit
said I wouldn't be in the shit if I could have shit
I wouldn't have backed out to back it out
if I could have shit
so I wouldn't be in the shit if I could have shit
