Oh darn, I missed this one?
Well, just call me "She Who Ressurects Old Threads." Anyhoo, my top picks are:
-From the Brook Shields episode of TMS, right before the Jabberwocky scene.
Scooter: Make this a good intro, Chief. This scene needs all the help it can get!
Kermit: Well, at least you're in the scene so you know what it is.
Scooter: (pulling a "Wha-a-t?" face) Have you seen the scene? Even when you know what it is, you don't know what it is!
-From MCC
Any scene with Gonzo and Rizzo interacting as Charles Dickens and...Rizzo.
Robin as Tiny Tim, and then later Kermit/Cratchit's "meetings and partings" speech.
-From MTI
Gonzo: This feels really weird.
Rizzo: You mean that Mr. Arrow's dead?
Gonzo: Yeah. That, and my pants are filled with starfish.
Rizzo: You and your hobbies!
Tim Curry as Long John Silver. If anyone can play a good villan, period, he can.
-From MFS
Seeing Scooter again!
Pepe in a tutu, okay?
