As he's shooting baskets, a boy joins him in the gym. He's wearing a retro jersey, and Stu doesn't recognize him. He tells Stu to come back later, and he'll give Stu tips. Stu returns, and the boy named Randy helps him with his shooting. Stu asks Randy when he went to school there, but the boy disappears. Stu discovers Randy is a ghost. Randy helps Stu make the basketball team, and Stu chooses to wear the ghost's number on his jersey.
