I was doing research for work today and came across
this article on text messaging.
Included in that article was this picture:

The picture was snapped to show the Korean text messaging in a subway station, but the ad behind it is what I want to talk about.
This ad came out while I was living in Korea, and I remember seeing it for the first time as I walked down the stairs into the Gyeongbok-gung subway station. I nearly tripped.
I remember this because I was so infuriated I wanted to come back and take a picture, but by the time I made it back to that station again, the ad was gone - whether for the same reasons that had made me so upset, I'm not sure.
You see, the advertisement was for a skin whitening creme.
