Leonardo has been funny since he was born: he was a funny baby, he was a funny toddler, he was a funny first-grader. But now, his teacher Mrs. Gomez asks him to stop being funny so that the class can learn. He tries his best, but he just has to make a funny face, then tell a funny joke, and then show a funny drawing - with predictable results. And when he finally seriously promises faithfully never to be funny again, he makes the teacher laugh so hard she falls down on the floor laughing!
