Mason Madrid is more than just the class clown - he's the class comedian. He's clever, funny and always on the lookout for ways to make his classmates and teachers laugh. Fortunately, his teacher (Ms Evans) keeps Mason on a tight rein to ensure that his jokes don't go too far or last too long. One day, the class gets some bad news and a substitute steps in for Ms Evans. Mason is delighted because he knows that substitute teachers are never as strict as Ms Evans. To his surprise, however, THIS substitute is a former class clown himself and he blocks Mason's every attempt to disrupt the class with his humor. But this substitute also appreciates Mason's talent for making people laugh and suggests to Mason that he might be able to use his sense of humor for a higher purpose. This gives Mason an idea and (with the help of his best friend Ezra and the unwelcomed help of Brandy - the girl who never laughs at Mason's jokes) he creates a video that is funny and inspiring. This is a story about the healing power of humor and how even a very funny kid makes a difference in someone's life.
