Answer:
I found Matilda and her Dad in the workshop scene the best.
Step-by-step explanation:
What happens is Matilda's dad shows his son how to lower the car mileage in this old car. Then Matilda tells her dad that he's a crook and that what he's doing is wrong. The dad gets flustered and tells Matilda that he's smarter than her and there's nothing she can do about it. Then she puts this glue in his hat and hands it to him. I find it funny because he doesn't know that his hat is glued to his head. Also because Matilda is really smarter than anybody in the movie.
