You might be an obsessed Muppet fan if you think you share secrets with individual Muppet characters.
I have a lanyard pin with a picture of Fozzie holding a banana to his ear, and above him reads "BANANAPHONE". My co-worker saw this and .... well, Let me just type our conversation verbatim.
Kathy: (looking at pin) I don't get it.
Me: (thinking how I would really rather not explain it)
uuuhhh.... Yeah, you wouldn't.
Kathy: What? What's that supposed to mean?
Me: I just wouldn't expect you to get it.
Kathy: Why not, I used to like Muppets too.
Me: Yeeaahh.... but this is sort of an inside joke.
Kathy: inside joke? for who? ! ? ...you and Fozzie Bear? ! ? ! ?
Me: .... .... .... Yes.
