I don't even have an example anymore. I just know whenever I watched those movies I felt so embarrassed and thought the jokes were a little too adult for me. Me. Myself. Thought that the jokes shouldn't have been used for someone my age. And how old was I? Much younger than now.
But then again, I could be mistaking all of these experiences with old Disney movies or something.
That's probably it, because as far as I know, (and I know Muppets very well) Muppet humor is pretty clean.
