This is a game I vaguely remember from some of the old forums, but whether it was Lum's, or Waterthread, or Corpnews, or any combination thereof, I cannot tell, so feel free to tell me I'm an old, forgetful hag. Anyway, it goes like this: Some pic is posted, like this random one I hereby start the domino line with: Now the next person in line posts a pic that has something, anything, in common with this one. Could be another guy in an ugly shirt. Could be some different bird. Or you could be more detail-oriented, like being a Harry Potter buff and knowing that is an eagle owl, and post a pic of Draco Malfoy; or recognize this was taken at WDW's Animal Kingdom and post another pic from there; or whatever. Try and make the link something recognizable for the benefit of your fellow denizens, or smugly post some obscure link in the knowledge that nobody else will get it, I'm not here to judge. The next person in line then posts something that links to your pic, and so on. Aaand .. go!
Ok that other thread got pretty obscure. Maybe every poster should say what the relation is to the previous image (in spoiler tags?).
