flexagon | So tell me about Sesame Street...

I want to learn about the world of Sesame Street so that I pick up any allusions I might see in Avenue Q next week. I know the following:

Pretty much everyone in the show lives on Sesame Street. Right?

Ernie and Bert live together. Ernie is the short one, and Bert is the taller one (and more serious or something, so Ernie makes fun of him). Some people think they're gay.

Big Bird is uh... Big Bird. I don't know anything about him. Can he talk?
Glover is the blue one with the red mouth. Ditto.

The Cookie Monster is also blue. Mention this one and people sing C is for cookie, that's good enough for me. So, that must be his song. :)

Oscar the Grouch lives in a trash can.

The Count does mostly arithmetic. He says things like ONE bolt of lightning. Mwa-ha-ha-ha-ha! TWO bolts of lightning...

Kermit the Frog... well, until last night I thought he was a muppet, but now I know he's on SS as well. He's a reporter. This is the only one whose profession I know anything about.

Snuffalupagus (spelling?) is a big wooly mammoth that only kids and puppets can see.

I doubt I can ask a question like this publicly without facing the question of how I could grow up in this country and not know more than that. Well, a, there was no television for me to have seen it on, and b, from what I hear it was mostly reading-centered, and I learned to read so early I can't remember it. So, yup. Culturally deprived.

Is there more I should know about the world, the relationships between the characters, etc?
