Two best friends are so excited to go back to school. They're in the same class, their classroom is full of art supplies, and they've even made a new friend. But then it happens: Just as the teacher introduces herself, the GIGGLES show up! They're everywhere and impossible to escape. And as if that wasn't embarrassing enough, soon a GUFFAW shows up, and then the CHUCKLES! What will their teacher think if they can't avoid laughing in the middle of her first lesson?
