OK, so how about this one?
This one should be bigger and better.
BRIAN HENSON INTRO
BRIAN: "Hi, I'm Brian Henson. Groucho Marx of the Marx Brothers was the oldest guest star to appear on The Muppet Show. He was 86 years old at the time. He & the other 2 of the guests, George Burns & Senor Wences, were born before the 20th Century. In this episode, Groucho would sing 'Lydia The Tatooed Lady', which is one of my father's favorite songs, to Oscar, a Muppet Grouch who was performed by Carroll Spinney, one of the Muppeteers who was a major performer for another Muppet Production called Sesame Street. Big Bird, also performed by Spinney, made an appearance in another episode. Here's The Muppet Show with Groucho Marx... & Oscar the Grouch."
STYLE: Early Season 2 (replacing the Zero Mostel episode)
COLD OPENING/DRESSING ROOM
SCOOTER: "Groucho Marx! Uh, Groucho Marx!"
GROUCHO: (in a rare TV appearance without the cigar) "Don't tell me! I know what you're going to say. 'Groucho Marx, Groucho Marx, 20 seconds.' It's should be 5 seconds from now--"
(The clock that is beside Groucho rings.)
SCOOTER: (off-camera) "That's a 15 Second Clock."
GROUCHO: (close-up) "What?"
OPENING THEME
"It's The Muppet Show with our special guest star Mr. Groucho Marx! Haahh!"
(Oscar the Grouch replaces S & W's comments.)
OSCAR: "Groucho is a 'grouchy' name."
Gonzo blows a cigar rathern than a horn. Smoke comes out of the cigar. ("Smoke doesn't come out of that horn")
You know why I don't usually make the whole script together? It's because I need some break from hard work of making scripts.
