This is one of the most neglected and un-thought of parts of your body. (It is also a part of non-fiction books, but that doesn't matter until you need to write a research paper.) Nobody really ever thinks about it. Like the tonsils, the backs of your knees, and the backs of your ears, we don't really ever think about them until something happens to them. The appendix is actually a mass of lymphatic tissue connected to the intestines, where the immune system can collect and dispose of bacteria and other harmful organisms that we swallow along with food. But, unfortunately, the passage between the two is very narrow, so sometimes stuff gets caught there, and it begins to fester.
Hey! I just read about the appendix. It is such a cool organ.

A common dish served by Asians. I first had grilled appendix at a place called Grandpa's Basement. It is low on calories and tastes similar to a cheese dog. Grilled appendix is worth the extra weight you will gain from this dish!
"What is that called?"

A written example of a balrogs tail whip. An appendix to an article which serves information that uncomfortably captures you, and pulls you down into deep darker issues. These issues have been present all along but the appendix unavoidably presents them to you.
