The Dark Shadows Alphabet Game

U is for upper lip.....[spoiler]what Roger and Elizabeth unfairly expected Carolyn to sport after her father's death
[/spoiler]

V is for vehicular homicide.  And it wasn't with Barnabas behind the wheel.

Overnight, The DS Alphabet Game passed "WB ORDERS FILMING OF NEW DS PILOT" and became #1 for most replies.

W = Bobbi Ann Woronko  Nurst Pritchett

Don't look at me.

Alright, how about X for the mark on the stage floor the actors used to find their places in front of the camera.  Grayson Hall always seemed to be looking for hers with those steep downward glances whenever she walked across the set.

Y is for "You gotta/have to/don't need to [delete as appropriate] understand!" (many times a reply to "I don't understand.")

Z is for those zany time-travelling adventures many of our beloved characters find themselves on

A is for Almanac, as in the book many refer to for information and photos. 

B is for basement, the place where many Collinses hid their secrets.

ProfStokes

C

Crystal's center (find it)

D is for Destroy  I think everyone at one time or another was threatened to be "Destroyed"

E is for the Evans Cottage

F is for forever.

G is for "Get out, Barnabas!" - one of my favorite lines on the show, spoken by Julia in Vicky's room not long after the end of the 1795 storyline.

H is for handyman, like Tom Jennings had been before he, um, found another "occupation"
