"This page is for Wikipedians to list articles that seem a bit unusual. These articles are valuable contributions to the encyclopedia, but are somewhat odd, whimsical, or something you wouldn't expect to find in Encyclopædia Britannica. We should take special care to meet the highest standards of an encyclopedia with these articles lest they make Wikipedia appear idiosyncratic. If you wish to add articles to this list, a broad consensus amongst contributors has identified two main guidelines. If the article in question meets one or both of these categories then it could possibly be deemed "unusual":
1.The article is something you would not expect to find in a standard encyclopedia.
2.The article contains some form of juxtaposition that most people would find unusual. eg Killer Cockroach, Henry VIII in Space, edible computers"
