Making the princess laugh, or smile, is a common fairy tale motif of various uses. The culmination of Golden Goose and The Magic Swan, where the goose or swan causes other characters to stick to each other, is that the sight causes a princess to laugh for the first time, resulting, as in this story, in her marriage. Peruonto and the frame story of Giambattista Basile, however, combine it with a curse, caused by the angry person laughed at, to force the princess to marry someone.
