Dairy Gum

When Gian and Suneo use Nobita as a scapegoat after breaking a bald man's window, Doraemon gives Nobita the "Say it for me" gum to make Gian and Suneo confess their mistake. But after a fall Nobita goes to confess the mistake to the bald man instead. However, he is praised by the bald man for being honest and is given all the baseballs he had confiscated from the boys.
