Panel 2: "Sesame Street Unpaved" is a cool book about Sesame Street with lots of pictures, lyrics, information, etc. The page in the cartoon here is supposed to be talking about Big Bird's tiny head.... When Big Bird first appeared in the pilot, he had a small bird-brain-ish head instead of the nice big fluffy feathery head he was given shortly after and still has today. (Then the next page shows a picture of Oscar the Grouch's original look: bright toxic-orange fur. Weird, huh?)
