It seems that we often buy products that are endorsed by celebrities and athletes. When you look at this add you know that Carl's Jr.'s instant salads are not necessarily enjoyed by Kim Kardashian and it gives you false hope of becoming in great shape as herself (although the salads will guarantee you an enormous ass comparable to hers). As humans we always want the best of the best because it often makes us feel superior to those who do not have the best of everything. This plays right into celebrities endorsing products because we think that whatever they are using is the best. So naturally we want to be like them.
