In the John Denver episode, after Kermit informs everyone that John Denver had invited them to go camping at the swamp, and they all try to get out of it, Miss Piggy threatens them into going. But right before threatening, she starts her speech with "We're going on a camping trip overnight". Considering how she emphasized the "overnight" part, I wonder why she'd want the others there. Without them it'd just be her, Kermit, and John Denver. From her point of view, wouldn't the less be the better? And at the end, when Kermit informs John that it's just them, John talks about catching frogs, making Kermit decide he'll find somebody else to go camping with. But wasn't it John who invited them to go camping in the first place? When I see him joke about catching frogs it looks as if he's trying to get out of going on the camping trip (maybe it was his idea but Kermit suggested the swamp?).
