When Annie and Bridget told Buster and Mary Jane that they were to attend a fancy dress ball given by the Plumbers' Friendship Association, the temptation for mischief was too great to be withstood by Buster and so he offered to secure the costumes. Annie and Bridget agreeing, Buster, Mary Jane and Tige trudged off to the costumer's and proceeded to pick out something that would make their friends the "observed of all observers." Back they danced to the house to exhibit their prizes to the servants. The two girls were just as happy as children, and proceeded immediately to dress for the ball. As usual in the Brown household, complications now became the order of the day and the arrival of the minister set things going in most approved Buster Brown style. It was Bridget who answered the bell and when the minister caught sight of her portly form all rigged out in the tarletan skirts of a ballet dancer, it was all he could do to keep a straight face. Bridget, however, tried to carry things off with dignity and ushered him into the parlor while she went upstairs to announce his visit to Mrs. Brown. In the meantime, Buster decided to bring the goat into the house so that he could see the two girls in their ballet costumes. This, of course, brought on more complications, which culminated in the wild stampede of the two servants right through the parlor where Mrs. Brown was trying to explain matters to the minister. The girls were quickly followed by Tige and the goat, with Buster and Mary Jane bringing up the rear, and in an instant, the Brown household was in a state of uproar bordering upon pandemonium.
