Synopsis:
While Lois and Lana stay at an upscale hotel to help publicize the grand opening, Superman conducts youth experiments at his Fortress. That evening Lois finds Superman changed into a baby outside the hotel. Lois and Lana take turns babysitting the child. Each girl uses hypnotism on Superbaby, so that when he returns to normal, he will marry them.

Superbaby flies away after a short time. When Superman arrives later at a party, Lois and Lana each expect him to propose, when he doesn't, the girls admit their plan to him. He takes them to his Fortress, where they discover that the Superbaby was from a parallel world. When he returned to his own world, he reverted to Superman and proposed to both Lois and Lana. Since bigamy is legal on the parallel Earth, that Superman married both girls.
