Skinning a bear should aggro every bears

Apparently linked to the then-upcoming 2.1.0 change where mining nodes aggros nearby mobs, a blood elf paladin created this legendary thread on the US Forums:

Skinning a bear should aggro every bears

in a 40 yard radius. It makes sense, you are actually skinning their best friend.

On 1-April-2008, Blizzard included this line in a facetious video about a hypothetical Molten Core console game.
