Popeye, Olive Oyl and Brutus are all at the home of the (stereotypical) German professor's house-lab watching the scientist show off his new "youth machine." It puts an old chicken in it, and out comes a baby chick!
After the vain Olive asks the professor if he could make people younger, Brutus volunteers Popeye to try it out. He then hits the "baby" switch on the machine so Popeye comes out as a little tyke. "Very funny," says an upset little Popeye, "now get me back to me old abnormal self!" Brutus replies, "Now run along and play with the other kiddies, Shorty!!" He then gives his sadistic laugh. He then grabs Olive.
How does Popeye get out of this "humilerating" experience? Well, he actually uses his brains more than his brawn. However, with this "strained spinach" we get hilarious finish and and ending with some justice. It's more of a "cute" cartoon than a laugh-out-loud one.
