Perhaps it is because I have trouble taking advice from a koala. I haven't seen a poster with a koala on it trying to teach me something since the third grade. Obviously someone was granted 60 or 70 billion dollars to research and find out what group of people was having the most accidents at work. They undoubtedly compiled reams of raw data and fed it into a computer, which analyzed the data and found that the most accident-prone group had just completed the third grade. Someone forgot to tell the computer that not all third grade students are eight years old.
Most people see the posters with the koalas and assume it has to do with daycare or something.
The people who need the posters would be to embarrassed to admit to their friends that they like koalas, and besides, they can't read anyway. The whole bear idea is supposed to be aimed at kids. The reason Smokey the Bear is so successful is not because grown men from Arkansas read Smokey the Bear pamphlets, it is because the children of the grown men from Arkansas read Smokey the Bear pamphlets and stop their dads from doing things like drinking Everclear with a lit cigarrette in their mouth. By the way, for those of you who live in a place where Everclear is illegal, like California, it is something like 199-proof grain alcohol, and it will kill you. Undoubtedly the whole crew watches the same cartoons, but it's not something you talk about.
