Chimney sweeps Stanley and Oliver go about their job, reducing Professor Noodle's living room to a shambles in the process, while the mad doctor works in his laboratory perfecting his "rejuvination formula." Cackling with glee, the Professor demonstrates his success for the boys, dropping a duckling into the vat and winding up with an egg. There's a somewhat different type of regression, however, when Stanley accidentally knocks Oliver into the formula.
