I had to take down the post on the skull purses with the silly commie logo in Chinese, because, well, they were just too ugly. I mean they were u-g-l-y. How ugly were they? Uglier than a two headed lamb.

As we used to say on Compuserve, ROF,LMAO.
(Showing my authentic claim to geekdom, there.) Ten points if you know that acronym.
