The special wastes no time by introducing the cast and the concept all within the first shot! The camera pans around a house with the main cast scattered around preparing for the show as Wally, the show's writer/host types the script in the foreground.
[The main set resembles a large house, yet in many ways marks a good prototype of The Muppet Show's backstage set what with Wally's table in the foreground and the staircase leading up to doors with stars on them in the back. You'll notice a slight similarity in color and design on this set as what was featured on "Captain Kangaroo" during the seventies.]
Wally announces the show's about love and asks aloud what can be said about love. Mildred, a purple birdish-looking quasi-elegant lady with long nose says love is a simple thing which leads the cast into singing the opening number, "LOVE IS A SIMPLE THING".
The rest of the main cast includes dog Rufus (from "Hey Cinderella"), George the Janitor, a long-nosed gloomy Frackle named Droop (Snivelly, modified from "Great Santa Claus Switch"), old man Brewsters, and everyone's favorite frog, Kermit. Midway through the song, Wally introduces the show and the guest star, Mia Farrow, who sings a verse in a cutaway heart. As the Muppets conclude the song, the final cast member, Crazy Donald (who would later become Crazy Harry - the puppet's the same, just an inexplicable name change) sings "love is to do your thing" and sets off an explosion in the room, giggling maniacally.
Wally tries to figure out more about love by consulting other members of the cast with little success. Droop's too involved in self-pity so Wally writes on his typewriter "George walks in." George enters, unenthused: "You typed?" The janitor wants nothing to do with the subject so Mildred and Brewsters add their input which doesn't add up to more than Brewsters chasing Mildred around.
Wally: You see, George, now there's two people caring for each other.
George (mocking): Caaaaring for each other. Dynamite!
At the mention of dynamite, Crazy Donald blasts a hole in the wall. Kermit tries to philosophize about love but the rest of the Muppets are too concerned over the hole to listen. Undeterred, Kermit hops over to the piano (with a chorus of singing frogs with banjos popping out of it) and sings a different-than-what-we're-used-to "Froggy Went A Courtin'" as we witness Kermit's courting of Miss Mousey and his duel with Big Mouse (Miss Mousey rides off with Droop on his motorcycle after the two combatants thoroughly bruise each other.)
[This number marks the debut of Kermit riding a bicycle, a simple marionette effect that would become the big deal about "The Muppet Movie". Most Muppet fans know that Kermit rode a bike two years before the film in "Emmett Otter's Jug-band Christmas" but only the sharpest fans are aware that this is Kermit's premiere cycling appearance.]
Wally figures it's time for the guest to arrive. Overhearing him typing this in the script, Droop yells out that Mia Farrow's here and the cast tramples over Wally rushing to the front door, then again to the back door when they don't see her there. A disheveled Wally points out the side door. Farrow enters, greeted by the cast who notice her rather obvious pregnancy. Mildred sits Mia down to chat over crumpets, to which Droop notes their crumpet died. The ladies chat more about Mia's becoming a mother.
Mildred: Some girls have all the luck.
Mia: Well, it takes a bit more than luck, Mildred.
Mildred: I KNOW, I know!
Mildred offers some cookies and comes across a still alive crumpet (which she tosses to Rufus to fetch). Wally arrives with a card to Mia from Thog, "Be my Vallentune" The card turns into the background of a set where Mia sings a vallentune to Thog (a giant blue monster from "Great Santa Claus Switch"). They sing "Real Live Girl", deliciously ironic since Mia of course IS the only real live girl in the program!
Next on Wally's script, "Charming lady guest star has chat with lovable dog type person". Mia asks Rufus to help her decide what kind of dog to get. As Mia considers her options, Rufus mimes what Mia says: tap-dancing when she mentions a showdog, donning a bus driver's hat and steering wheel at the mention of a greyhound, etc. Finally Mia concludes she doesn't want a dog...unless it could be a dog like Rufus.
Mia and Rufus then sing "How much is that Doggy in the window". [This song has been edited out of this special when it has re-aired on television. In February 1993 when the pilot was shown on Nickelodeon and February 2002 when it aired on YTV in Canada.]
As the Muppets chase Crazy Donald around in the background for another blast, Wally ponders love on other planets. Cut to Kermit, reprising his reporter's role from "Sesame Street" reporting from the planet Koozbane on the time of courtship. A male alien meets a giggling female and dances crazily around her. The female laughs and whips the male with her long nose (!) signaling the legendary never-before-seen-on-television Galleo Hoop Hoop.
The two march far away from each other than run toward each other eventually colliding, exploding into a quartet of baby Koozebanians. [This sketch would be performed again in episode 7 of The Muppet Show, starring Florence Henderson.]
Wally wonders if George got anything out of the show but George sweeps him away with his mop. Mia gets George to realize that he has love in his life as well...he loves his mop.
This realization prompts the closing number, "I've Got Love" as all the Muppets from the special (even the Koozbanians and the crumpet) join in. In one rather interesting shot, Wally dances around with Kermit! Adding a sense of parallelism to the opening number, Crazy Donald ends the song with an explosion.
As the credits roll, the Muppets line up to kiss Mia good-bye (echoed somewhat later during the end of the Paula Abdul episode of Muppets Tonight). Before she can kiss Kermit, Brewsters cuts into line for another kiss. At the end of the line, putting in some cameo appearances are Rowlf the Dog (most famous for his regular appearances in the Jimmy Dean Show) and Ernie and Bert (from Sesame Street). Rufus follows Mia home as she exits.
