Some of my favourite PB stories include the one where the Elixir of Life is spilled all over a photo album, and the pictures come to life, constantly repeating what they were saying when the picture was taken (So you have, for example, half a policeman who got in the shot saying "Pass along, p-, pass along, p-").
