From Says Uncle:
Prior to this weekend, our master bedroom was a color called China Doll. Now, every penis-bearing person reading this is thinking China Doll is not a color, its an oriental figurine or the name of a porn star. See, China Doll is a very, very light shade of brown or possibly a dark shade of white. There is some debate in the scientific world of color evaluation as to what color it really is. We (and by we, I mean the wife) decided that we needed to change from China Doll to Apple Butter. Again, penis-bearing individuals are thinking that Apple Butter is something you put on biscuits or the name of a porn star. Apple Butter is a slightly darker shade of brown (or possibly white, were still not sure) than China Doll.
