Saturday morning blues

When I was young things were very simple.
Tv had 5 channels, I was too small for a pimple.
There was a guy who painted happy trees.
Another guy swung on vines, what a breeze.
There were energy blades and a crazy caveman.
A book reading cat, even an apearance by Captain Marvel, SHAZAM!

I sat there in rapt attention
To discover Mr. Wizards next invention.
My moms best mixing bowl, full with captain crunch.
there I awaited the Hair Bear bunch.
Half a gallon of vitamin D.
waiting for the next program, what shall it be?
