Here's a few from my childhood:

Oh beautiful
For spaceship guys
God shed his skin on thee,
And crown thy good with Robin Hood
From sea to shining sea



They're coming today
To take me away
The men in the little white suits.
They think Im insane
'Cause I think I'm a train
But I really am! TOOT! TOOT!

I hate Bosco
It's full of TNT
Mommy puts it in my milk
To try to poison me
Buy I fooled Mommy
And put it in her tea
Now I have no mommy
To try to poison me.

(Whatever happened to Bosco, and Cocoa Marsh, for that matter?)

And all the countless kids' verses to Popeye The Sailor Man probably deserve their own thread, but stuff like this abounded:

I'm Popeye The Sailor Man
I live in a garbage can
I eat all the worms
And spit out the germs
I'm Popeye The Sailor Man, TOOT! TOOT!

And somehow, versions of WWII songs were sung:

First Marine ate a bean, parlez-vous
Second Marine ate a bean, Parlez-vous
Third Marine ate a bean
and Phhhttt! all over the submarine
Hinky-dinky parlez-vous

First Marine jumped a fence, parlez-vous
Second Marine jumped the fence, parlez-vous
Third Marine jumped the fence
And milked a cow with a monkey wrench
Hinky-dinky parlez-vous

(There was a whole thread's worth of verses to that one, too)

All For Now,
