These might be repeats, i didnt have time to read all of these comments, just found this page but had to contribute. THanks for sharing all of these! I loved these.

sung to: Off We Go Into The Wild Blue Yonder

Off we go into the lunch room yonder
pushing girls out of our way
Forward boys start moving down the counter
Grab your grub, fill up your tray.
Try the beans, they were prepared last Friday
and the meat's tough as a mule
The soup is cold,
The breads got mold, YECH!
anything beats our lunchroom at school.

Oh how I loved these parodies. I'm 63 and still have them in my head.

Sung to: As the Caissons Go Rolling Along

In a test
for a class
that we know we just cant pass,
see the goof offs go faking along
start to heave, fake a chill
anything so you'll look ill
as the goof offs go faking along
For its hi hi hoo
lets all fake the Asian flu
Shout out your symptoms loud and strong
Blah, Ech!
we will feel enthused
when the teacher says excused
as the goof offs go faking along.

Cant remember the actual tune of this one.
Cheat em all
cheat em all
in the springtime
the winter
and fall.
those Lincoln quotations
we hide in our fist
that Longfellow verse
written on our left wrist.
If you find,
that your mind cant recall,
the date when the Romans took Gaul,
a glance at your kneecap will help you recap
so why take a chance
Cheat em all!
