I got this really cool biography DVD on sesame street. I got it from the biography channel. Its really cool. They show you about all the muppeteers, and they show you interveiws with them, in which they somtimes say what it is like playing a certain character. It also tells you about some of the problems that they somtimes run into while writing a show. It shows some of the people that were on the show when it first started,back in the day. There is tons of other cool stuff on it. You should buy it and check it out.
