Obviously I'm Up to Something

If I stumble across this:

“A parody must convey two simultaneous–and contradictory messages; that it is the original, but also that it is not the original and is instead a parody. To the extent that it does only the former but not the latter, it is not only a poor parody but also vulnerable under trademark law, since the consumer will be confused.” From Cliffs Notes, Inc. v. Bantam Doubleday Dell Publishing Group, 886 F. 2d 490 (2d Cir. 1989). (Via Chilling Effects)
