One thing I've always thought was odd was a quote from Joan Ganz Cooney in the book, saying that when Jim was negotiating with Disney, he wanted his contract to allow for him to spend two weeks a year on Sesame Street when he never spent two weeks a year.
Seems like a surprise to me. I would have thought he spent at least two if not more weeks working on the first season, since there were so many inserts that year and he tended to perform whoever was starring in each insert (being one of only three main performers that season). Sure, most of the ones from the first season used either Ernie and Bert's apartment or that beige-colored background and they could have easily shot several in a day with those sets, and in the early years it was common for scenes to be shot in one take (to save on tape/film), but it still seems like the first season had an awful lot of segments for him to have just worked on it for two weeks. I wouldn't be surprised if he worked on the show for less than two weeks a year during the 1980s, though.
But still, maybe Jim did manage to do so many segments in less than two weeks (after all, there were only a few months between the test shows and the first broadcast episode), or maybe Joan was misremembering/not counting the first season, or maybe she meant he never worked on the show for two weeks in a row (but then again, I'm pretty sure that that part of the contract allowed for two weeks a year, not neccessarily two weeks in a row). And I would like to think that the "two weeks on Sesame Street" clause would also include working on additional Sesame Street projects (specials, albums, talking toys, Sesame Street Live, etc.).
