In a commercial called "The Ex", Citi Card illustrates the benefits of their credit cards through the story of a sad sack "boring, boring, boring" guy who's girlfriend breaks up with him. This ad preys on the stereotype of men just wanting to sit at home and watch TV.
To be fair, I don't think this ad necessarily puts the ex-girlfriend in a great light. It presents her as superficial and shallow, herself. I know Citi needs a 'hook' for their commercials, but I don't think it is necessary to disparage people.
