I’ve never seen 30 Rock (I KNOW, I KNOW) so I can’t attest to the correctness of this, but supposedly the show is a rip-off of The Muppet Show.

EXHIBIT B: LIZ LEMON VS. KERMIT THE FROG
Both are the most normal characters on their respective shows. Both are unlucky at love. Both are neurotic worrywarts and type-a personalities who slow burn into a crazy breakdown once per episode. AND both have some kind of flirtation with the guest stars that ultimately goes nowhere. There is absolutely no difference between Liz Lemon and Kermit the Frog save for genitalia (Liz is a lady, Kermit has none).

Make up your mind, internet. Is Kermit Liz Lemon or Christian Bale?

Update: Sesame Street did a 30 Rock bit. Liz Lemon was played not by Kermit but by a lemon. (thx, elisabeth)

Four months before the opening of The Empire Strikes Back, Luke Skywalker, C-3PO, R2-D2, and Chewbacca appeared as the special guest stars on The Muppet Show. Mark Hamill’s first line as Skywalker is:

It seems we’ve landed on some sort of comedy variety show planet.

…and it goes downhill from there. The whole show is available on YouTube in three parts:

The appearance was probably orchestrated as a promotional crossover. Frank Oz voiced Yoda in Empire and was a lead puppeteer for The Muppet Show, performing Missy Piggy and Fozzie, among others.
