Insensitive joke about "No Pork" Indian in Singapore

I actually have to think really hard before posting this. On one hand I can see how this might appear really funny, but this also comes across as being really insensitive. I think racial harmony is something that we in Singapore absolutely cannot take for granted; I just hope that this is only an isolated incident, a thoughtless prank aiming for a good laugh, instead of an emerging trend among our population.
