Mental-O from New Freak by PEDIGREE
The Pedigree is a concept invented by man to make everyone believe that dogs should be judged by how they look instead of how well they can do things. In order to still look a certain way they will make dogs fuck their whole family and then you get really stupid dogs. Pedigree is multiple dogs from the same musical scene fucking each other for so long that you get this big stupid deformed beast.
