Bobby's parents are confirmed spiritualists, and Bobby, disobedient as ever, decides to play a practical joke on them, tying thread to all the vases and other parts of furniture. Bobby allows the servant to put him to bed. When he is supposed to be sound asleep, Bobby gets up, and while the spiritualistic seance is taking place, Bobby begins to pull the tables and vases over onto the heads of his parents, who are scared and think this is the work of the spirits, until the servant discovers Bobby in his nightshirt busy with the spooks, or in other words, the thread.
