Has no one noticed the subtle satire in the original post? It lies in the analogy between jokes and music.

Lynne made the analogy, as if it weren't implicit in the original post.

I think the whole thing was written to satirize the idea that one shouldn't download music from the Internet.

It's not a perfect analogy, but it makes a point.

If I have spoiled the joke by explaining it, I apologize, but it seems no one was getting it anyway.
