The prolonged laughter over kangkung may be a sign of something deeper. Just as the Bersih yellow was the symbol of dissent over the unfairness of the present electoral system, the humble kangkung has become a symbol of the economic difficulties facing ordinary Malaysians.

Given that outward expressions of dissent (e.g. street protests) are strictly curtailed, the laughter over kangkung provides a ‘safe’ outlet for the pent-up frustrations of many people who are feeling the burden of rising prices, low incomes and the impact of corruption and cronyism.

For the BN, whether it is the yellow of Bersih or the green kangkung, the effect is just as embarrassing.
