For some reason the title of this thread reminds me of one from my summer-camp days in the 60s:

Whistle while you work
Hitler is a jerk
Mussolini bit my weenie
Now it doesn't work.

As for "The Battle Hymn of the Republic", there's

Mine eyes have seen the glory of the burning of the school,
We have tortured all the teachers, we have broke the golden rule,
We have went into the office and we shot the principal,
The school is burning down!

Glory, glory for the burning of the school (3x)
The school is burning down.

(Sic. I might even say sic transit gloria.)

On the subject (and possibly from San Francisco?),

Ta-ra-ra-boom-de-ay,
There is no school today!
The teacher passed away
Because of tooth decay.
We threw her in the bay;
She scared the sharks away.
