For Jamie: :0) How to spell BUNK(C)O???

So we have an ongoing discussion on how to spell BUNK(C)O! Is it with a "C" or a "K"??? I always spell it with a K, because I have a soft spot for K!!!! My hubby is Kaleb with a K, not a c, which is different. So, I went to my usual place to find out things: I googled it! And you know what, it is spelled both ways!!! You can find it with either a C or a K and it means the same thing. So, for the purpose of this sight, I am going to stick with my K (because I would have to change a heck of a lot of things if I didnt! :0) But I leave it up to all of you to decide how you want to spell BUNKO!!
