My film partner thinks we should leave it out.

A parody exists when one imitates a serious piece of work, such as literature, music or artwork, for a humorous or satirical effect.

"…the use of some elements of a prior author's composition to create a new one that, at least in part, comments on that author's works."
- "Parody" as defined by the U.S. Supreme Court
"…the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified by that section, for purposes such as criticism, comment… is not an infringement of copyright."                     -Section 107, U.S. Copyright Revision Act
