   “The best of friends become the worst of enemies when Barney makes a hilarious attack ad where he viciously pummels a cardboard cut-out of Homer before special guest star Linda Ronstadt joins the fun to both continue the attack on the helpless Homer stand-in and croon a slanderously accurate, insanely catchy jingle about how “Mr. Plow is a loser/And I think he is a boozer.””

   “Case in point, as Lichfield detailed on Twitter last week: Almost as soon as the "hipster effect" article was published, a man furiously emailed the magazine claiming a photo of him was slanderously used alongside it without his permission. He was, it turned out, mistaken.”
