Here are a couple I didn’t see above:

Glory, Glory Hallaleua (sp?),
Teacher hit me with a ruler
shot her through the floor
with a loaded 44
and she don’t teach no more!


My eyes have seen the glory
of the burnin’ of the school
we have tortured all the teachers
we have broken all the rules
…


Look at [insert dorky kid’s name here]
doin’ it, doin’ it
pickin his nose and
chewin’ it, chewin’ it
Thinks it’s candy
but it’s not
It’s a snot
with a cherry on top


dumb joke:
Ask “What are you eating under there?”
When the kid asks, “Under where?”
You say, “Eeeww, you’re eating underwear!!”
