He is known for coining quirky catchphrases, such as "cheaper, better, faster" and "upturn the downturn".
Yesterday, NTUC secretary-general Lim Swee Say dropped two new acronyms - QED and CBD - to describe his take on the labour movement's goal of twin-growth in productivity and wages by 2020.

Using cartoons, graphics and his signature brand of wit, he said: "When I was a student, my favourite subject was Mathematics. Every time a question was asked and we came up with the answer, we put down three letters - QED."
Drawing laughter from his audience, he added: "I should have told the professor to give me something more challenging."

On the mammoth task of creating better jobs and salaries for everyone, Mr Lim said: "Yes, I believe this Can Be Done".
