Twenty years ago - in the mind-numbing aftermath of the terrorist attacks on America - the immediate, mind-numbing response of the media was to ban laughter. All laughter, including jokes, chuckles and guffaws. This is the story of what happened next. With contributions from Private Eye to The Onion, via David Letterman, the News Quiz and Have I Got News for You. As well as 9/11 and the death of Bin Laden, Joe Queenan explores the pandemic and the US retreat from Afghanistan.

"What a year 2021 has been – from the storming of the capitol in Washington to the fall of Kabul to the Taliban, this has not been a good time in the US. Probably not so great in the UK either. Throw in some riots, add in the climate crisis and the plague – none of this is worth the slightest lame joke. But is it worth a good joke?"

With contributions from three US presidents, plus Ian Hislop and Adam MacQueen from Private Eye, Armando Iannuci (creator of The Death of Stalin), Susan Morrison of the New Yorker, and Robert Siegal editor of The Onion in 2001 - the first US publication to break the laughter ban with the headline, US Vows To Defeat Whoever It Is We Are At War With. A copy of that magazine is now in the Library of Congress.

Also includes archive from David Letterman, Linda Grant, Michael Rosen, Rich Hall on Have I Got News for You, plus the News Quiz from September 2001.

Joe Queenan is an Emmy Award-winning US broadcaster. His previous contributions to Archive on Four include Brief Histories on Blame, Shame and Failure.

The producer for BBC Audio in Bristol is Miles Warde.
