MCA minister Wee Ka Siong's recent video conference questioning the Penang government over the undersea tunnel project has irked its chief minister.

"If I am a lecturer and Wee is my student, he would fail. He does not seem to understand my lectures properly. He would surely fail in his exams," Chief Minister Lim Guan Eng told Malaysiakini today.

"How petty he can be? So just to make him happy I will say that we did not pay a single sen nor did we pay by a square inch to the contractor for the undersea tunnel," Lim quipped.

Saying he does not want to waste time responding to Wee, Lim said the MCA vice-president was merely trying to divert public attention from his own 'failures'.
