It's like your face

To make a good commersial, you don't need an actual marketing idea. You don't need to have a good product and you certainly don't need to be intelligent. What you need is a bunch of good looking women / men who pose in underwear in some sort of sexy way. Just to attract people to look at it, get interested in the shitty product and then eventually buy it. Just to find out that the actual product is useless.
