Today, signs have taken over all human lives. Meanwhile, advertising is a sign system that has captured people's minds and eyes all day and night. In the meantime, celebrities are occasionally made to increase the amount of advertising penetration in public. In this regard, the purpose of the present article is to present a kind of mythology and a demythologizing of the hidden reality behind the text of the advertisement. In this study, in the form of semiotic theory and analysis of Barth's mythology, two ads have been analyzed to determine the implicit meaning of the second order of the message and the text.

Eventually, the study concluded that these myths represent a reality and show the situation more ambitious than what it is, and thereby reach out to many audiences.
