Yesterday, a barely remembered comment from a Terry Pratchett novel about a professor at Unseen University sent me to google to look up from which book it came. The professor in questions was commonly referred to as the "reader in the loo" or something similar, but the results that came up for that sentence (sans quotation marks) sent me off on a tangent. Among the search results on the first page was the following Wikipedia entry, which has to be one of the weirder ones to be found in that estimable encyclopaedia (not that the entry is in any way silly, but it's weird that the subject made it onto WP in the first place). It's a long entry, too:
Wikipedia: Toilet paper orientation
Apropos of this, here is a challenge for you, Dear Reader: To find a more unexpected or strange Wikipedia entry and post it as a comment to this post.
