You’re teaching a class
And in someone barges.
You want to protect
Both yourself and your charges.

So what do you do?
Grab your bucket of stones
And soon the intruder’s
A bucket of bones.

Your students can help
If they each grab a rock,
Assuming they aren’t
Immobile with shock.

Just think how effective
Such tactics can be!
We all can join in
On a stone-throwing spree!

Of course, if the trespasser’s
Wielding a gun,
The pupils (and you)
Might be tempted to run.

For certainly studies
(Most likely) have shown
A bullet’s more lethal
Than any thrown-stone.

And let’s not forget
There’s a lot here at stake.
An innocent guest
Could be ****** by mistake.

This foolish idea
A school district condoned.
Makes me wonder if they
Were in other ways ******.
