I heard that PBS had to edit some of the episodes so they don't get the R rating. On HBO they can show shows with an R rating. Then edit them so they are PG or G later on. Little slips like Cookie Monster smoking and eating a pipe, a lost girl going into Mr. Hooper's apartment because he has milk and cookies there teaching kids to go with strangers, stuff like that.
