Greetings and Good Tidings my fellow Geeks! I thought I'd try to suggest a fairly simple game and see how far it'd go.
1. State a Head-cannon: Any belief you have of a Fandom of any sort, you can state it here.
2. The next person who wants a turn must state "Approved" or "AND--".
3. State the next head-cannon or attempt to add-onto the previously stated head cannon.
I think Morticia Addams' home town was Nightvale (of which is part of the Lovecraft universe, there for she's an inter-dimensional being like Cthulu), and her legs are tentacles that are bound together by her very tight dresses so she can show off her optimum height or to imitate her husband's race just a tad.
