Fake Shemp

Okay kiddo, imagine you are watching a movie with your family and suddenly one of the actors gets sick or is unavailable to work anymore. The movie still needs to be finished, right? So instead of leaving that character out of the movie, they hire someone who looks similar to the missing actor to fill in for them. This person is called a "fake shemp."

The term "fake shemp" comes from a famous comedian named Shemp Howard. He suddenly passed away in the middle of filming a movie, so the filmmakers had to use a double to finish his role. Since then, anyone who fills in for an actor in a movie or TV show is called a "fake shemp."

Sometimes, the fake shemp will be filmed from behind or wear a mask to cover their face so you can't tell it's not the original actor. Other times, they will be filmed from a distance or only have a small part in the movie.

So, a fake shemp is basically a stand-in actor who replaces the original actor when they can't finish filming their part. It's like pretending someone else is the actor just to keep the story going.
