30 Rock, a clear rip-off of the Muppets

Tina Fey's 30 ROCK is currently the most acclaimed comedy series on television. It's won numerous Emmys and Golden Globes and I think Pulitzers. Critics and audiences alike love the show and its lovable zany characters, and consider it one of the most original comedies in years.
And I guess it is original...if you've never seen THE MUPPET SHOW. Because, my "friends" (in quotes because I don't know or trust you, please don't be offended), Tina Fey's 30 ROCK is quite obviously ripping off Jim Henson's beloved TV show.
"You're crazy", you say? "Wow, now with the insults. This is why I don't trust you", I respond. And the I hit you up with so many facts you HAVE to concede I'm absolutely right.EXHIBIT A: THE PREMISEEach week, our smart yet neurotic lead character has to manage a group of wacky misfits and put on a weekly sketch comedy show. Which show am I talking about? 30 ROCK plays like NBC went to JJ Abrams and told him to reboot THE MUPPET SHOW. "Do what you did with STAR TREK. Make it hipper, more adult. Maybe lose the puppets to allow more time for product placement."EXHIBIT B: LIZ LEMON VS. KERMIT THE FROGBoth are the most normal people 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).
