Yes, they exist--according to PETA:
LINKNow ordinarily, one might be upset by this display of sheer stupidity, but I'm taking a more pragmatic approach. Given the fact we can't kill them (yet), it's still nice to know who they are for when it becomes time to cull the herd. After all, even animals shun their stupid and sick so they 1--can't breed, 2--get eaten by others, thereby ensuring survival.
This is just making our jobs a little easier when the time comes.
