This is one from my school, we made it up near Christmastime if that wasn't clear.

[To the tune of "O Holy Night"]

O Sunday Night, the school is brightly burning...
It is the night that we burned down our school.
Long lay our class, reports and essays writing...
Till we appeared, and set all rooms aflame!
The shrill alarms,
And all the teachers screaming,
As yonder loom
The strong and mighty flames.
Fall... on your knees...
O hear... the sirens wailing...
O school, be-gone...
O school, we hate you so...
Our school... is gone...
Ashes, forever gone.
