Last week I was reading this post about a famous Muppet's sketch with Fozzie and Kermit (featuring in episode 110), so I watched it (the video can be easily found on several streaming service, and, even more easily, on the internet).
I must admit that my English is quite bad, and in fact, even after watching it with subtitles several times, the joke is still unclear to me:
what is the connection between Kermit's "bear" and Fozzie slang "No, he-is-a-not, he is wearing a neck-a-tie"?
why Stadler, when asked by Waldorf at the end of the sketch if he understood the joke, replied "no, but I don't speak Italian" ?
Given that I AM Italian, I am quite interested in understanding the dark of this joke.
I googled it quite a bit, but as of now I've found no clear explanation.
