Seinfeld sued for calling author a "wacko"

We read:

"A kid's cookbook creator is still trying to take a bite out of Jerry Seinfeld, the New York Post reported. Missy Chase Lapine, whose suit against recipe rival Jessica Seinfeld was thrown out of federal court last year, is now taking aim at her funnyman husband in state court. She says the TV star slandered her during an appearance on the Late Show with David Letterman, when he referred to her as "angry and hysterical" and a "wacko" stalker. In a later interview with E! News, he referred to Lapine as a "nut."

Ms Lapine's state Supreme Court suit says she's none of the above - she's simply a cookbook author who suspected Seinfeld's wife of stealing her ideas and recipes for her bestseller, Deceptively Delicious...

Ms Lapine sued both Seinfelds in federal court - Jessica for ripping off her idea and Jerry for ripping her - but a judge found Jessica hadn't stolen her book, and said the slander case should be heard in state court.

If everyone who got insulted went to court over it, there would be a huge traffic jam in the courts so the outcome of this could be interesting. As far as I can see, insults are protected free speech but whether any of it constitutes libel is the interesting part.
