I am not sure if this has been covered here. My wife and I were watching an episode of Bear in the Big Blue House recently with our daughter. She asked me about how the Bear was operated. Well, needless to say, I had never given it any thought. It's like Big Bird as well, I never thought much about it. Well, curiosity has me bringing it up here for discussion. Any thoughts on the Bear operation? How many people does it take, ect.. ?
