The hilarity is in the footnotes.

The Food Lion case referenced Hustler Magazine v. Falwell, 485 U.S. 46 (U.S. 1988).

Hustler ran an a parody ad that suggested Reverend Falwell had sex with his mother in an outhouse.

The good Reverend sued.

The Supreme Court said, “Welcome to life as a public figure. Denied.”

From the case:
The inside front cover of the November 1983 issue of Hustler Magazine featured a “parody” of an advertisement for Campari Liqueur that contained the name and picture of respondent and was entitled “Jerry Falwell talks about his first time.”

This parody was modeled after actual Campari ads that included interviews with various celebrities about their “first times.” Although it was apparent by the end of each interview that this meant the first time they sampled Campari, the ads clearly played on the sexual double entendre of the general subject of “first times.” Copying the form and layout of these Campari ads, Hustler’s editors chose respondent as the featured celebrity and drafted an alleged “interview” with him in which he states that his “first time” was during a drunken incestuous rendezvous with his mother in an outhouse.

The Hustler parody portrays respondent and his mother as drunk and immoral, and suggests that respondent is a hypocrite who preaches only when he is drunk. In small print at the bottom of the page, the ad contains the disclaimer, “ad parody-not to be taken seriously.” The magazine’s table of contents also lists the ad as “Fiction; Ad and Personality Parody.”
And the holding:
Here it is clear that respondent Falwell is a “public figure” for purposes of First Amendment law. The jury found against respondent on his libel claim when it decided that the Hustler ad parody could not “reasonably be understood as describing actual facts about [respondent] or actual events in which [he] participated.”

The Court of Appeals interpreted the jury’s finding to be that the ad parody “was not reasonably believable,” and in accordance with our custom we accept this finding. Respondent is thus relegated to his claim for damages awarded by the jury for the intentional infliction of emotional distress by “outrageous” conduct.

But for reasons heretofore stated this claim cannot, consistently with the First Amendment, form a basis for the award of damages when the conduct in question is the publication of a caricature such as the ad parody involved here. The judgment of the Court of Appeals is accordingly.
