The plumber, a powerful fellow, decides to give up his trade and become a soda fountain clerk in order that he may compete with the small, well-dressed clerk, his rival, for the hand of little Miss Moffett. He eats more than he sells, but the proprietor is afraid of him and dares not discharge him. It happens that the stylish little clerk brings little Miss Moffett in the ice cream parlor for refreshment, and when the plumber serves him with a castor-oil sundae he becomes peeved. An egg throwing contest then ensues in which the plumber proves to be the best marksman.
