Don't we love these kind of ads...

Personally these are my favorite ads. It is an instant attention grabber. It amuses the viewer and that is exactly what a marketer is looking for. After all, a big majority of the products we purchase made their way to our houses simply because the commercial or the packaging drove our attention.
Human beings are extremely curious. Therefore, using the ads above is a perfect way to satisfy their curiosity and thus eventually lead them to consume.
