Hee hee, these are fun!  It wouldn't be a dream curse if Sister Helene didn't show up in mine, probably giving her "Girls who cross their legs are easy" speech. 

 Others here I'm sure would find their own Sister _______ behind one of the doors.  Stand back in case she's swinging a yardstick, whew!
Even more frightening would be Amanda Harris squealing "Queeeeeeeeentiiiiiiiiiiiiiiinnnnn"!   Brrr!!!
Speaking of Donna McKechnie, did anyone watch NBC's 75th Anniversary?  They showed a clip from Hullabaloo, and I've read here that she danced on it pre-DS and sure enough, there she was.
