Once saw a TV ad, find particularly interesting. Is a photo printer ad. Whole family were to travel, taking lots of pictures back. After returning home with their own color photo printer to print the photos out. I was surprised that a few penguins, everyone knows penguins covered in only two colors, black and white. So for them, and no use color printer, specifically how the matter back do not remember, just remember that a few penguins funny look.
