well, when you have 2 cats that over 10 pounds each, and they tend to intimidate him, SO....we figured to make up for his size we would give him a name that the cats would fear! HAHA.
Not to mention the giggles we people ask his name and we tell them 'Thor'.
I told Rob it is simply that he has a complex over having such a tiny dog and needed to be able to tell friends..."yea, I got a dog, and his name is THOR."
They, of course, expect a pit bull, not a little 2 pound furball with a ponytail!!
I have pics on my myspace of him

His album is the only one set to EVERYONE so that everyone here can view his pics with no problems
