A parody is often considered noninfringing under the Fair Use provision of the Copyright Act. Under the Act, the four factors considered when making a determination of fair use include: (1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes; (2) the nature of the copyrighted work; (3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and (4) the effect of the use upon the potential market for or value of the copyrighted work. 17 USC 107. Most parodies are found to satisfy the fair use criteria. Irony is not necessarily parody nor is perhaps "make fun of another avenue", which sounds like satire.
