The yellowed pages of about 400 books at a Southwestern Ontario library didn't come naturally.
Unless you count nature's call -- which has reportedly resulted in some $8,000 in damages to books at the Leamington Public Library near Windsor.
Police are on the lookout for the repeat offender. In addition, the library has installed $5,000 worth of camera equipment in an effort to catch the peeing bandit.
Destroying the affected books -- about 400 volumes, some costing as much as $100 each -- has been a number one priority for library staff.
"As soon as they’ve been touched with a biohazard ... we would not circulate them to the public, they’re destroyed,” chief librarian Janet Woodbridge told The Toronto Star.
“You can’t recover books.”
According to the CBC, staff are now patrolling the library every 15 minutes, hoping to catch the person responsible for at least four urine attacks in the last three weeks.
“That is disgusting,” regular patron Barb Newman told The Windsor Star. “My heart sank when I saw all the books missing."
As for the offender's motives, there doesn't appear to be a specific genre being targeted, but the books under fire are located in parts of the library not often frequented.
"They don't appear to be making any editorial comment," Woodbridge told the CBC.

A <a href="http://thestir.cafemom.com/teen/136092/state_senate_declares_holding_hands" target="_hplink">bill passed in Tennessee earlier this year declared hand-holding</a> a 'gateway sexual activity,' with teachers facing firing for even demonstrating the action.
Surprisingly, the ban on hugging isn't a one-off rule at a select school, but a trend that seems to be spreading. Schools in <a href="http://abcnews.go.com/blogs/headlines/2012/03/new-jersey-school-bans-hugging/" target="_hplink">Portland and Florida started instituting these rules</a> in 2010, while administrations in New Jersey, Brooklyn and <a href="http://thedailyedge.thejournal.ie/new-zealand-school-bans-hugging-448032-May2012/" target="_hplink">New Zealand took it upon themselves in 2012</a>. For all, the reasoning appears to be the same: Respecting personal space and "unsuitable interactions" between students.

Due to its "aggressive" nature, <a href="http://www.nytimes.com/2001/05/06/us/increasingly-schools-move-to-restrict-dodgeball.html" target="_hplink">dodgeball has been banned in schools across North America</a>, as it's frequently named the cause of injuries and fights.

You'd think, with all the talk about childhood obesity these days, schools would be encouraging students to ride their bikes or skateboards to school. One New York <a href="http://www.foxnews.com/story/0,2933,559460,00.html" target="_hplink">said it was illegal for kids to have bikes</a>, while another Orthodox school <a href="http://www.yourjewishnews.com/Pages/20640.aspx" target="_hplink">disagreed with the freedom afford by the two wheels</a>.
There's plenty of debate about the best possible bookbag for kids -- but one school in Michigan doesn't allow bags into the classroom at all. Citing safety concerns in lunchrooms and classes, <a href="http://www.mlive.com/news/jackson/index.ssf/2009/09/no-backpack_policy_challenged.html" target="_hplink">the high school asked students to keep returning to their lockers between classes</a> to retrieve the appropriate books.
There have been many toy bans in schools, but Pogs -- those tradeable metal disks -- made a huge splash when t<a href="http://www.nytimes.com/1995/03/22/us/to-end-pog-fights-schools-ban-game.html" target="_hplink">heir safety, and the competitive rush spurred by their very existence</a>, was called into question by schools around the world.

The school claimed it had <a href="http://jezebel.com/5055243/boys-makeup-gets-him-banned-from-school-what-lesson-does-he-learn" target="_hplink">a rule against "extreme or distracting" makeup</a>.

Silly Bandz are fun! Silly Bandz are cute!

Milk was always seen as part of a wholesome school lunch, but now a group of doctors wants it off the menu entirely. A vegan and physician group in the U.S. is pushing a petition to get rid of milk in schools, <a href="http://www.huffingtonpost.com/2012/07/25/ban-milk-from-school-lunc_n_1703406.html" target="_hplink">due to it being "...high in sugar, high in fat and high in animal protein that is harmful to, rather than protective of, bone health</a>."
Well, not dinosaurs <i>exactly</i>, but the word dinosaur, in addition to other words like "poverty," "birthdays," "Halloween," and "dancing," which <a href="http://www.huffingtonpost.com/2012/03/26/new-york-city-bans-refere_n_1380991.html" target="_hplink">might elicit "unpleasant emotions" in students.</a>
It might get chilly in Pennsylvania, but students there won't be allowed to wear their sheepskin Ugg boots into class, <a href="http://ca.shine.yahoo.com/ugg-boots-banned-in-school--education-crisis-solved-.html" target="_hplink">thanks to the potential for storing contraband like cell phones in the roomy footwear.</a>
You may have thought baggy pants were more of a '90s thing, but schools today are continuing to push for bans on the sagging pants, with <a href="http://www.dailymail.co.uk/news/article-2020259/Saggy-pants-ban-Florida-school-board-plan-new-rules-pupils-dress-code.html" target="_hplink">some schools claiming it interferes with learning</a>, and <a href="http://www.huffingtonpost.com/2012/05/31/saggy-pants-ban-at-chicag_n_1559248.html" target="_hplink">others saying the style is related to gangs</a>.
And then there's the opposite end of the spectrum. Much like yoga pants, skinny jeans have been banned in schools all over the place, due to their lack of modesty and <a href="http://articles.nydailynews.com/2012-03-22/news/31227071_1_dress-code-skinny-jeans-tv-station" target="_hplink">distraction factor for the opposite sex</a>.

Grinch, much?
