Two more missed ideas
Came up with 2 other jokes they didn't think to do:
1. When Kermit comes out to introduce the gulag revue, he could've also said this, "I just want to say something about the gulag. I didn't like it here at first, but I did find out something good about it. From my cell window, I can see the state of Alaska!"
2. Miss Piggy is singing the Titanic theme song and in the audience we see Leo Dicrapio (I don't like him) and Kate Winslet watching this and this dialogue occurs:
Leo: You know, I've always hated that song.
Kate: Yeah, me too. And now I hate it even more.
Leo: Me too.
Or something to that variety.
Then when Constantine interrupts the song and Miss Piggy complains they stand up and say, "No, that's fine."
