Humour is a useful tool in helping to cope with cabin fever during a lockdown. Jokes, memes, and funny one-liners engage people remotely and create a sense of social belonging. Paul Lewis, the author of “Cracking Up: American Humour in a Time of Conflict,” believes that jokes amid the outbreak offer a real shelter. “People usually make jokes about everything, but when news narrows down and has this element of fear, jokes are a way of temporarily triumphing over and repressing it.”
