If you want to create something that will appeal to internet surfers, keep this in mind: the essence of comedy is the juxtaposition of opposites. When you combine the pleasantness of something cute with the excitement of something popular but not cute, you get a surefire hit -that is, if you have the talent to pull it off. In these mashups, the “cute” comes from the popular toys of the My Little Pony series, which provides the adorably shaped horses and a dose of nostalgia for those that grew up with them. There’s no end to the horror that artists will mash with the ponies. See some of the best in this article I wrote for mental_floss.
