If you stay in Potong Pasir, make a trip to dr ng visit and try
something interesting:
With all the media present, ask him how does he think A-Chiam is
doing.
In public, he will have to reply in a positive note for A-Chiam and
if he is smart enough, he will continue by adding that sito will be
able to do more than A-Chiam.
Here is the trick. Be smarter than him. Once he finish commenting
about A-Chiam and just before he can start his add-on about sito,
say "thank you for your comment" and immediately ask another
non-revelant question to cut off his addon.
Have another friend take a video of your interview. It will be
interesting to see his expression when you cut him off.
