Comedian Joan Rivers ran dry with Adele insult but Adam Hills' return jibe fell flat DOES a fattist insult justify a sexist one? There's been much hi-fiving online this week among Adele fans (and aren't we all, love her sick), who are delighted by the way local comedy hero Adam Hills took down Joan Rivers for making fun of the singer's weight. The veteran comedian went on David Letterman's show after the Oscars and made cruel fun of Adele's post-baby body. She said she'd met the singer at the event and then made a "she's thiiisssss big" gesture by spreading her arms wide and puffing out her face.
