Appearances can indeed be deceiving. In their fairy tale “The Bremen Town Musicians,” the Brothers Grimm highlighted this idea with a special lesson for younger generations. An ass, hound, cat, and rooster are each rejected for their age, but their wisdom and wit come from their years of experience, not from their looks.
After years of carrying sacks to the mill for his owner, the ass has grown old and unable to perform his duties. Knowing his limitations, the ass guesses that his master will put him out to pasture, so he runs away. Since he cannot serve his master, he sets out to seek employment in Bremen as the town musician.
