Do you remember The Electric Company? If not, just go read about it here. I watched this show every day in the early 1970’s, right after Sesame Street. It was a collection of skits intended to help kids learn stuff. I loved it because it always started with someone screaning "HEY YOU GUYS!!!!"
I looked it up today, mostly because I don’t really remember much about it, beside loving it. I was surprised to see how many famous people were responsible for it, including Morgan Freeman, Bill Cosby, Gene Wilder, Mel Brooks, and Joan Rivers.
I was also impressed with some of the content they managed to get. There was always a Spiderman skit, and that was lisenced to them for free. There were also Looney Tunes shorts created by Chuck Jones specifically for TEC.
There’s LOTS of good info at the wikipedia page for it, check it out.
