Commercials are filled with logical fallacies. Often, they appeal to either pathos or ethos. Sometimes, they use some celebrity that has absolutely no connection to the product to promote the sales. In one commercial, Pawn Stars host Rick Harrison promotes single blade razors. Not only does Harrison not have any credentials to give credence to the company's ploy to get people to buy their product. Harrison talks about former Presidents used single blade razors to get the smoothest shave possible. This reason to buy the razor has absolutely no validity because Presidents are normally not experts on shaving materials, and if they are they should be experts in politics.
