Mulberry is at it again; without Miss Farnaby's permission he takes it upon himself to enter her into a quiz. Although she is initially reluctant to acquiesce, in the end Mulberry finds a way to persuade her. At the same time, Bert and Alice plead their innocence in Mulberry's decision, unaware that Miss Farnaby has already agreed. When the pair discover he has convinced her to go in for it, they can't help feel a little usurped.
