Neil Gaiman was recently on the Wits American Public Media podcast where he got to read the "worst of the worst" of their "Bad Gaiman Challenge": paragraphs that tried (badly) to imitate Gaiman's style of prose. You can listen to the whole episode here or listen to a funny skit with Gaiman called "Alternate Realty" here.

Personally, I think the story about the man with the boring job who suddenly meets Brunnhilda was very, very good and I wanted to read more of it. But all of them were very Gaimanesque.
