There are business benefits to laughter in the showroom. According to Alison Beard's Harvard Business Reviewarticle, Leading With Humor, laughter in the workplace reduces stress and boredom, increases engagement and well-being and spurs not only creativity and collaboration but also analytical precision and productivity.
A little self-deprecation goes a long way. When you laugh at the receiving end of a joke, your mental load is lightened. According to the Mayo Clinic, when you laugh at yourself, it causes your brain to release endorphins and can also stimulate circulation and increase muscle relaxation both of which help to reduce the adverse effects of stress. When you decrease stress in the workplace, you increase productivity and lower absenteeism. Not all humor is productive. Off colored jokes can be a turnoff and a potential liability for the company. Good clean jokes that don't demean anyone are good for business. Harvard Medical School professor Carl Marci claims, "Laugher is a social signal among humans. It's like a punctuation mark."
