Get these douches off my fb..?

You can remove them from your friends list, block them, or have it where they can't comment on your newer posts. To remove them, just go to their profile, click the gear (if they have the new timeline profile), and go down to "unfriend". To block them it's the same thing, but click "report/block" instead. To have them not see your posts, go to your privacy settings (http://www.facebook.com/settings/?tab=privacy) and click "custom". Here you can put their name in the "hide this from" section. I'm not sure if this will unable them from posting on your wall, so blocking or removing them will probably be the best thing to do.
