Normal vs Different

Part of my daily routine includes feeding my 19 pound pug his daily meals. Once in a while I notice that some of the pieces of dog food are a little out of the ordinary; probably 1 out of 20 scoops before I come across one of the different looking ones. To me, these different ones are so much more interesting. In print, television, billboards, viral or any form of communication design, there seems to be that different piece of dog chow that seperates itself from the normal looking ones.
