Making an average apple shine

I watched part of the Grammys last night. One of the performances had Taylor Swift (who I believe is 21) with Steve Nicks of Fleetwood Mac (who I am guessing is ~60). It struck me how young Taylor looked next to Stevie. Don't get me wrong, she looks young on her own, but the contrast with Stevie made her look even younger. She seemed 15! By the same token, Stevie looked older than I think she would have on her own. I told the boys about this, and how one can make something look better (or worse) by showing next to something else. Take an average apple and show it next to a gorgeous one, and people will probably rate it worst than if they saw it on its own. Or, show it next to a rotten one, and people will rate it higher. The boys wanted to know how to make the rotten apple look good. We came up with a few ideas, but I think I'll leave them off the blog ;-).
