Something rare

This cartoon is unusual in two aspects.

Firstly, I deviated from my usual drawing style.
Secondly, I used Singlish (or Colloquial Singaporean English).

Using Singlish in a national paper is a big no-no.
Somehow, this one slipped through the cracks and got published.

For readers who are unfamiliar with the slang,
the word "Geng" means "Pretends to be ill".

And "MC" is short for "Medical Certificate".

 Oh, and army barracks are often riddled with paranormal tales/sightings.
