I learned this as a child from my Dad who had so much of this stuff in his head that for years he'd still be able to surprise us with something we hadn't heard before. I remember riding down the road with my pals, a trillion miles per hour on bicycles, bellowing it as loud as we could. Oh to be young again...(Oh yeah, I just told Corey I was still young, on another thread.)

Up in the air with the junior bird men
Up in the air and upside down
Up in the air with the junior bird men
Keep your noses to the ground
And when you hear the grand announcement
That their wings are made of tin
Then you will know the junior bird men
Have sent their boxtops in

You need five boxtops, four bottombottoms, three wrappers, two labels and one thin dime.

Jeez, I haven't sung this in ages. What fun! Thanks.
Peace, Mooh.
