Oh, yeah, I have wondered about Fuzz for quite a while. He/she/they are like an annoying ugly dry itchy patch of skin that won't go away no matter what you do to it, and it is there all the time.
I've actually wondered if Fuzz is a demented profane reincarnation of humblegunner. There are some similarities but not enough to make a solid case.
Gross, see a dermatologist.
Demented and profane? Most definitely.
Humblegunner, not a chance in hell.
