Family Guy, a television show, made a derivative of the song,When You Wish Upon A Star, with a song entitled,When You Wish Upon A Weinstein (I Need A Jew).The skit was poking fun at Disney's wholesome image and the frivolousness of wishing on such things. When sued for infringement, the best defense would probably be:

De minimus use

Fair Use, because it was a parody

Fair Use, because it was a satire

Lack of access
