Yeah I get kind of tired of seeing fanfictions naturally assuming last names work on ponies as they do on people...especially when they add to existing ponies like "Shining Armor Sparkle".... that just sounds silly.

I mean look at the Apple-family, sure most of their names are apple-related but the word Apple only apply to a few, often not even in the right order (compare Applejack and Apple Bloom to Caramel Apple, or Braedburn and Big Mac.)

Sure there's the cakes but that just seems like theme-naming. Wouldn't make much sense if Cup Cake was Cup Pear or something before marrying...
