Following a recent incident in a London theatre where, it appears, Jewish Israelis were targeted by a comedian because they wouldn't stand for a Palestinian flag, Howard Jacobson reflects on the power of mockery and the liberation of laughter.

'Do the best comedians truly turn the world upside down', Howard asks, 'or do they merely strap us into a fairground roller-coaster so that we can feign fear and scream in unison?'

He argues that the norms of outrage have been jettisoned in the reaction to events in Israel on October 7.

'Once the world is turned upside down,' he writes, 'humanity and justice fall like loose change from our pockets.'
