Not only does it titillate my humour-friendly fibers but the encouraging letter allegedly sent by SecondLife.com to the creator of the Get a First Life parody displays what is, to me (IANAL), perfect legal sense.
Frivolous lawsuits and cease-and-desist letters are detrimental to the overall legal system involved in content creation (especially in the U.S. but also in other regions where the lobby groups such as WIPO are prominent). By showing that they apparently don’t intend to threaten a parody site, SecondLife’s lawyers show more than humour and common sense. They show an appreciation for the positive side of legality.
More power to us!
