this so called obscene movie

I don't get it. There's a Swedish film called I am curious Yellow/Blue. Back when it was made in 1968 it was banned in Massachusetts for being obscene and pornographic. Now in this modern day the children's cartoon Ed, Edd and Eddy named one of their episodes I am curious Ed. How could a movie which is considered to be obscene be the inspiration for a children's show! I wonder what that episode is like. Does Ed kiss his lover's flaccid penis? I hope not. That would be just too weird. I found this movie (it's actually two separate movies, Yellow is part 1 and Blue is part 2) at the Rutland Free Library. Yellow, the first part was (to my surprise) taken out so I will have to wait till next week to take and it and watch this so called obscene movie.
