For me, it was Easy Reader by far.
Fargo North was probably second.
And of course, I meant to post this in Cafe Society.
Learn to read, idiot!
Spider-Man. Where was he comin’ from, Spider-Man? Nobody knew who he are!
It’s that Parker kid, dude. You need to read more.
Spiderman with Letterman a close second and Easy Reader third.
I could not wait to tune in next time when Spidey said wahwahwahwahwahwah.
Yeah, I used to watch Spider-Man on the Electric Company and then read the comics, and I refused to believe that under the mask Spidey could be such a goober.
I’m a big LetterMan fan myself. The things he could do with a silent “e”…
No votes for Naomi?
All of the above. Plus the Corsican Twins, Jennifer of the Jungle, the mad scientist guy, J. Arthur Crank, the Blue Beetle, and oh so many others.
While I’m here, lemme see if I can get some help on a couple of things, both of which I’m 98% sure were from the Electric Company. To confirm that I’m not insane, does anyone else remember the following:
-
“Kermit the Hermit, wisest man in the world.”
-
A cartoon where someone is imagining a story based on the cracks in her walls and ceiling. One looks like a camel, and I believe one looks like a monkey, and one is a monster, which they ultimately confront.
Anyone? Anyone?
What about her?
And no love for ElectraWoman and DynaGirl? C’mon people, that was Deirdre Hall’s finest work!
Are you sure that was the Electric Company? I thought they had their own Sid & Marty Kroft Saturday morning TV show. I was a big fan, though. I had my own masculinized version of ElectraWoman and DynaGirl, with self-made costume: “Wire Boy.” 30 years later and some of my parents friends still won’t let me forget it. 
That’s from Sesame Street. Bob was trekking through the wilderness, looking for Kermit the Hermit (who was a human being, not a felt-covered frog). Upon finding Kermit, he said “Tag. You’re it!”
That’s from The Krofft Supershow – not a bad kiddie show, but devoid of educational value.
Ah, the SDMB. It does not disappoint.
Crap, I could’ve sworn that was the Electric Company. My preschool mind merged an entire day of television into one show. And for the first time in ages, I feel young!
I remember The Electric Company fondly, but not well enough to remember specific characters. I was messing around on YouTube recently and found this hilarious clip, I vaguely remembered it:
I guess The Electric Company is where a lot of my sense of humour comes from! 
I still remember as a kid watching the Electric Company. Let me set the scene:
This long legged bird walks into the frame, squats, lays an egg, and leaves.
A cow comes along and sits on the egg for a while, then leaves.
The egg hatches, and a long-legged bird stands up, looks around, and goes, “Moooooo.”
Well, I was probably 5 or 6, just old enough to understand that there’s no way that bird would have been saying “moo” just because a cow sat on the egg. It friggin’ floored me. It’s possibly the first absurdist humor I ever got.
I explained it to my mom; I don’t remember her reaction, but it was probably a blank stare.
“It’s the plumber. I’ve come to fix the sink.” was a favorite of ours, too. I vaguely remember Letterman, and some of the others mentioned here.
Now I feel dumb…I came in here thinking people were talking about Louie the Lightning Bug.
Don’t forget “Love…of…chair”
