I think at one point I saw this, internalized it, and spat it back out as "This code is public domain. Please use it for good, not evil."
I know that this stuff is really serious business to some people, and they get frustrated by these random acts of frivolity. "Don't you know," they say with a stern face, "software licenses are no place for fun and games".
Pfffft. The license is awesome. I appreciated the joke when I first saw it, and am appreciating the ongoing humor it is providing.
I do see how it would prevent some organizations from using the code. Mostly those that have become large, risk-averse, and so disconnected from the community that they are actually, honestly afraid that Crockford is going to come after them for using JSMin for evil.
Sadly, Google apparently now falls into that bucket.
