Ways of Advertising!

I find it interesting thinking about ways people advertise, whether it be products or companies, or even themselves. When i was interning at cramer productions, i received an email that was interesting to say the least. It was a collection of pictures showing the ways people display advertisements. I believe humor is a good way to advertise a product, because it will make the consumer want to relate to that product. I want to pose this question to other viewers. Why do you think it is important to be creative with advertisement? Is it something psychological that fascinates our curiosity with ads, and thus will make us more inclined to use the product? Or is it something deeper than that.
