As Scrooge McDuck goes to the grocer's, the grocer announces that he is Scrooge's former schoolmate, Quacker Gander. Much to Quacker's dismay, Scrooge doesn't recognize him. Quacker is even more puzzled when Scrooge instantly remembers having seen that dollar bill somewhere before when Quacker gives him his change.
