Orrrr. My Father So Naughty

Saw this old packaging of the old water heater that I used when I was young. The heater is no longer around (I think), but the box is used to store other junk.

I think I know why my father bought this brand hor, even though it is not a very famous or popular brand. Wah. How come no R(A) ratings huh ? Movies that show so much, sure kenna slap with R(A) ratings one ...
