I saw this blog entry at Legal Insurrection. It points out the efforts of a group called Citizens for Sanity. The ad below ran in the Providence Journal. After due consideration I find I must disagree with the blog. This is not an example of parody. I would characterize it as satire. I have provided the definitions of both terms below. You decide.
noun, plural par·o·dies.
a humorous or satirical imitation of a serious piece of literature or writing: his hilarious parody of Hamlet’s soliloquy.
the genre of literary composition represented by such imitations.
a burlesque imitation of a musical composition.
any humorous, satirical, or burlesque imitation, as of a person, event, etc.Dictionary.com
the use of irony, sarcasm, ridicule, or the like, to expose, denounce, or deride the folly or corruption of institutions, people, or social structures: The success of the production stems from its balance of affectionate comedy and well-observed satire.
a work of art, literature, or entertainment in which the folly and corruption of human beings, institutions, or social structures are exposed, denounced, or ridiculed: The skit offended only those who didn’t recognize it as a political satire. Did you notice that all the novels on her bookshelf were satires?

Like the Gershwin song performed by Louis Armstrong and Ella Fitzgerald, ” you say to-may-to /təˈmeɪtə/ / And I like to-mah-to /təˈmɑːtə/” There may be little difference in the distinction. The mark of great satire is that there is an underlying factual basis. Had the pranksters included a caveat that those wetbacks who show up with their own rake, lawn mower or vacuum cleaner would be allowed to stay, the whole thing would seem straight to me.
