Uncle Arthur is supposed to make napoleons for dessert, but ends up bringing in Napoleon Bonaparte instead! Arthur cannot remember how to send him back and Larry wants to use Napoleon to advertise detergent. Unknowingly, Samantha says the right words and he disappears back to his own time.

A leprechaun sent by (who else?) Endora wreaks havok on Darrin by making him wear a pear of mint shoes that makes him lazy. Samantha stops him by making a potion that controls him and all other lecrechauns.
