Leonardo has been funny since the day he was born: he was a funny baby, he was a funny toddler, he was a funny first-grader. Now he is in grade four; and Mrs. Gomez asks him to stop being funny. 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!
