A completely unimportant question that is bothering me (so it’s perfect for the Dope).
During the Muppet Show and the Muppet Movie, Miss Piggy is in love with Kermit and imagines that they will get married and have little frig (or pog?) babies. Kermit does not reciprocate and is generally annoyed with Piggy. Then while my son is watching one of their numerous [del]crappy[/del] later movies Kermit and Piggy are girlfriend/boyfriend.
When did that happen?
The backstory in (a lot of? all of?) the movies is always that they were in love at some point prior to the movie, but then Kermit broke it off because he couldn’t handle it.
I don’t know if I can pinpoint it more specifically than: after The Muppets Take Manhattan. As you’ll recall, that movie ends with a wedding scene in the show-within-a-show of “Manhattan Melodies”. Kermit notices that the guy officiating isn’t who it’s supposed to be (as in, Piggy subbed in a real priest), and it’s left kinda vague as to whether Piggy sneakily married Kermit for real.
Then, Jim Henson died. The next movie, The Muppet Christmas Carol, has Kermit and Piggy playing the roles of Bob Cratchett and wife, with children. There’s no friction, and even though they’re playing parts, you’d expect to see some of the usual friction there, but you don’t. Ever since then, they’ve been pretty “out” as a couple.
Which movie? Were they playing other characters in the movie (as in, for example, Muppet Christmas Carol)? What was the nature of their relationship?
In any case, you may wish to consult the Muppet Wiki.
Which Muppet Movie are you talking about? In the one that had the song The Rainbow Connection, Kermit was head over whatever-the-back-of-a-frog’s-feet-are-called in LU-U-U-UR-R-RV-V-VE with Piggy, and it broke his little green heart when she ditched him in the restaurant.
And it was always my sense during the prime-time program that they were in fact an item; but he didn’t let that interfere with his commitment to professionalism.
And in the recent Jason Segall movie, it was obvious that Kermie and Piggy had shared a home together at one point (the front gates of his crumbling estate had both their faces on it). But as their success faltered, she skipped town and went to Paris to be the editor of Vogue.
Piggy thought they were. Kermit was not so sure. She even tried to trick him into marriage just like in The Muppets Take Manhattan but were saved by Lou Zealand and his Boomerang Fish Act.
I don’t think they ever had any kind of continuity on this. Their status suited the story and it was never really set in stone.
Well, whatever the story, we can assume it’s heartfelt.
And stomachfelt.
And armfelt.
Muppets are made of felt is what I’m going for, here.
Miss Piggy had a strong enough personality that it didn’t really matter whether Kermit realized that they were an item: She said they were, and therefore they were.
The boys will be frogs, the girls will be pigs.
I vividly remember watching that when I was a kid – I was seriously worried that Kermit was going to fall for the trick! How he gets out of it (and how they set up the Boomerang Fish thing earlier in the episode) is brilliant, and may get my vote for Funniest Muppet Scene Ever. I was crying from laughing so hard.
As for the Kermit/Piggy relationship, even as I kid I always thought he really did love her, in his own uptight, repressed way. He could just never bring himself to admit it/do anything about it because of A) fear of commitment, and B) the knowledge that Piggy was, let’s face it, a delusional, manipulative, violent lunatic. A lovable one, but still.
(This is all in regard to the TV show and the three Henson films; I haven’t seen any of the others and do not consider them canon, personally. :))
What about the Muppet Family Christmas? Henson even appeared at the very end. Miss Piggy and Kermit traded presents and were obviously together.
If they ever do get married and have kids, I hope they don’t ever let Elmo babysit! 
Shouldn’t that be Frogue? 
I’m In Love With A Big Blue Frog
Well, I’m not worried about our kids
I know they’ll turn out neat
They’ll be great looking 'cause they’ll have my face
Great swimmers 'cause they’ll have his feet
In Muppet Treasure Island, they were former lovers, and apparently Kermit had dumped Miss Piggy.
that’s a handful of deep thoughts there.
Whatever fit the narrative and is funny, I think.
But I get the sense that the default is that they are in love, but he’s got shit to do while she really doesn’t. And she’s an id and he’s a superego. And they embody '70s stereotypes about men and women.
Between the Gonzo is an alien thread and this one, methinks we Dopers might be spending a wee bit too much time pondering the canon of the Muppets.
