I own more than 100 DVDs or Blu-Rays.
Robette's collection is pretty big, and if you're counting individual discs then my Survivor collection alone is probably getting pretty close, but I don't really own a lot of movies since I lived at home until I was married and never really bought movies for myself.
I have never read a novel written by Charles Dickens or Jane Austin.
Had to read Great Expectations for school, and was later given a complete set of leatherbound Dickens volumes by someone who hated me, I have no idea why.
I've fired a gun
Main event of my bachelor party (not counting the car accident.)
I have been in both the northern and southern hemisphere.
Nope. Furthest south I've been is the Baja region of Mexico.
I like to sun tan.
I have a natural perma-tan from years spent working outdoors, but I don't do it on purpose.
Over the course of my adult life I have voted for at least two different political parties.
Conservatives mostly, but I voted for a third party in the provincials a while back when the Conservatives were randomly attempting to push a bill that would have nerfed free speech in the privacy of my own home.
I have had either my tonsills or my appendix removed.
Tonsils.
I have at least one (what I consider to be a) major allergy to something.
Nope. Minor allergies to cats, dandelions, grass, and trees.
I have donated blood.
So many times I'm eligible to be put on the wall of fame.
I believe in ghosts
Surprisingly, yes. According to the Bible some form of spirits do exist (as in the witch of Endor calling up the Prophet Samuel).

@Matt: Wait, what? You have to be of legal age to donate blood in the States? Weird.
