Spam can be highly annoying. But it can be used for some positive things as well:

Spam Music: Calculate a note from a spam message, and play it every time you a spam arrives. --JanneJalkanen
Babelfish it into Arabic so it will at least be pretty to look at. --Freerange
seed games of life with it, and see which spam builds something self sufficient? --Freerange
give your hotmail account to someone, and make one time pads from them? --Freerange
With all the talk about email ceasing to be a reliable transport, at least receiving your regular dosage of spam means that your ISP is not yet broken and your email still flows. --JanneJalkanen
You know what your friends read --MaxVoelkel
(corollary: you have a common enemy to hate and to talk about, which can function as a bonding experience - spam camps, anyone? --JanneJalkanen
