Mobil Disney Comics #4

Donald's disciplining of his nephews is witnessed by Prof. Pulpheart Clabberhead, a child psychologist, who convinces the duck that punishing children for their misdeeds will hamper their development. He soon learns that children without boundaries become spoiled brats, as the nephews take full advantage of Donald's new leniency. At the end of his rope, Donald invites the Professor to his house where the nephews set off giant firecrackers under his chair, proving that even an indulgent child psychologist can chase kids with a switch in his hand.
