What does arragon find in the cascade ?

Prince of Aragon is pretty full of himself and chooses the silver casket because he thinks he will "get what he deserves". Inside is a picture of a fool with the writing, "So be gone: you are sped. / Still more fool I shall appear / By the time I linger here / With one fool's head I came to woo, / But I go away with two." This basically says that only a fool would choose another fool.
