Kermit missing the diamond
Okay, let's suppose that you are watching this movie for the first time. You have known for a long time that the Muppets are just puppets, and you know that many characters don't have working hands.
You got all that? Good. Now, let's say that you have known for years that the Muppets are puppets, many characters hands don't work, and you know that many tricks are hard to master. Let's get to the baseball diamond scene. Better yet, if you haven't seen the movie yet and don't want the ending spoiled, go to another page or thread now.
Now, during the end, the Muppets are throwing and catching th baseball diamond. All of the characters who have the diamond in their hands are "live hand" puppets, meaning that their hands are operated by the hands of performers, and not arm wires, so they can move their hands and fingers more freely. Now, you know that Kermit isn't a live hand puppet. Near the end of the scene, Kermit has his hand up in the air, planning to catch it. Do you know that he won't catch it, because of the way his hands work, or do you think that Jim henson would go out and have some elaborate trick used for kermit to actually catch the ball with his hand?
