S1E13 · Starry Starry Night

Big and Small are outside at night, watching stars. Small is annoyed, as he thinks that stars aren't interesting at all, but after Big tells him that stars are actually big balls of fire, Small becomes more curious about them. He asks Big how many stars are in the sky, but Big isn't sure. After the two check a book about stars, they read that nobody knows for sure how many stars exist, so Big decides to be the first one to count them all. Small heads back inside, and Big begins counting the stars, keeping track of his count on a clipboard. He quickly gets interrupted by Small, though, and loses track of the stars he's already seen. He tries counting again, but still gets interrupted by Small. Annoyed, but not wanting to give up yet, he starts counting yet again. This time, he gets very far, counting up to the 200s. Small is getting bothered by all of Big's counting, though, so he asks if Big is done yet. Big loses track again, so this time, Small tries to help him.
