A Wikipedia entry that's sillier than what you find at Conservapedia:

Hard to believe, but true. Check out Mel's Hole.

On the page, there is this cautionary note:

The factual accuracy of this article is disputed.

UPDATE: The entry has come to the attention of a couple of Wiki-editors and they don't like it (although it may manage to survive as a Paranormal entry). It might get drastically shrunk or removed entirely.

As remarked in comments, it's got a charm all its own; it would be a shame if it were to go.
