I'd like to draw your attention to the Yahoo! Travel ad at the bottom of this image:
So let you and me have a quick talk, Yahoo!. If you'd like to encourage me to take a trip, please refrain from reminding me that I am pasty, white, and have a coral reef of fat swimming above my waist. And the picture of a man in your ad has reminded me exactly of this, because he is ripped, tan, wearing white capri pants, and holding the hand of a female model in red. Am I supposed to identify with this couple? Like "oh look there's me and Jill walking down some random beach in the southern hemisphere". Instead I am thinking "shit I haven't been to the gym in six days and had a bag of chips for lunch". If you want me to go, show a really fat dude with floaties around his arms holding the hand of an elderly woman pushing an oxygen tank. I might think "hmm i'm better then them I should take a vacation".
