Lol yeah, but as far as I know that's a falacy XD, like, you know? Value disassociation. When a person makes it famous, like that one serial killer who captured, r*ped and took photos of their feet's victims, that's one person. Does not mean that every person with the same, or smiliar qualities of that person will have similiar or equal behavior.
There was a research, or more like prof, that people who abuse and/or dispose of their pet have an extremly high chance of being psychopaths. But that is a much more direct line of thought, due to complete negligence for other, or lack of complete lack of compassion (Psychopathy).
With that said, I think feet are like one of most famous (as in most people have it) fetishes. Trough admitance of course, but who knows...
...(by the way sorry for completly going off topic from the joke there Xd)....
