Good question lol I know they pop off but the airbag gets in the way and im not going to start prying on that lol
They can be removed from behind. Got that hideous gold color out of there. http://i.imgur.com/BRouJaV.jpg
Remove the buttons and shit from behind it and remove the screws holding it in. I found a photo on eBay of a steering wheel with it removed which helps explain it.
