Exactly, and whatever adult humor was included in the Muppets - or anything Jim did for that matter - was never blue, off-color-, or inappropriate that kids couldn't enjoy it either way. Some of Jim's non-puppetry projects, I would say, are probably for "adults only," but only because kids wouldn't be interested in them: his experimental films like TIMEPIECE and THE CUBE wouldn't hold kids' interests . . . most adults wouldn't even get them either.
