I love whenever the muppets break the fourth wall, or react to another muppet as being very strange. Kermit is especially good at this, with that sarcasm he frequently employs (only directing it at the muppet in question when he's really annoyed) when he's more or less wondering aloud if anyone else finds this bizarre, or if he's the one who's crazy. I also love his, "This about this, folks," when he's doing something puppetly difficult, like drinking or blowing out a candle. It makes me want to hug dear Jim.
