People who attended the 2019 Pendulum Summit in the Convention Centre Dublin will be familiar with Boris Johnson's yarn about the movie "Jaws".
At the motivational speakers event, the future prime minister asked the audience: "Who was the real hero of Jaws?".
After fielding several mock answers, Mr Johnson unveiled the correct answer - not the Sheriff, not the shark - but the Mayor. Why? Because he kept the beaches open, and kept businesses in business.
Actually, I take it back. It's the shark, Boris.
Without the shark there would be no show business.
