James: They made this robot that looks like Philip K. Dick.
James: But now it's missing!
Ursula: ....dear lord.
James: If it shows up on the doorstep, distract it with the pink light!
Ursula: We don't have a pink light!
James: (horrorstruck flailing)
Ursula: MY GOD! What kind of crappy survival kit did we buy that doesn't come with a pink light in case of Philip K. Dick robot attack?!
...you probably had to read "Valis" for this to make sense. And I don't recommend it. This conversation was the most enjoyment I got out of that book, and it's sort've like getting a kick out've showing people the scar from your hippo attack.
(Believe it or not, there really IS a Philip K. Dick robot. http://www.boingboing.net/2005/06/23/philip_k_dick_robot.html The world is not safe.)
