Wow, I love the internet. I learned this at Silver Bay camp in upstate NY in the 1970w from a delightful old man named George Manos.

Up in the air, junior birdmen
Up in the air, upside down
Up in the air junior birdmen
And keep your noses off the grond

Oh when you hear the doorbell ringing (ring!)
And you receive your wings of tin (flap flap)
Then you will know the junior birdmen
Have sent their box tops in

It takes
5 box tops
4 bottle caps
3 labels
2 wrappers and
one thin dime!

Don't be a glutton get your Captain Marvel button!
Whoosh!
