WoWDB

From Wowpedia:

Source

This item has an extremely low chance of dropping of monkey mobs acording to the armory.

Trivia

This item and it's source is probably a reference to the Infinite monkey theorem stating that a monkey hitting keys at random on a typewriter keyboard for an infinite amount of time would almost certainly end up having typed a given text, such as the complete works of William Shakespeare.

It should be noted, however, that the Armory has been unreliable in the past.  (See Arcane Dust as a spell reagent for Enchanting as an example.  This is not the sole example, but it came to my mind because I pestered Blizzard for years to fix the listing...)

As WoWDB and Wowhead have never recorded a player looting this item, and seeing as The Undermine Journal has zero data despite Wowhead using it as a source for the listed Buyout price...  I am tagging this as not available to players.
