There is one little known fact that no one has mentioned here. Most humans have an inner ear mechanism made up of the Anvil, Stirrup and Hammer. Trolls have an extra bone called the Knowall that gives them discerning auditory capability.
Most higher-order mammals have that inner ear complement.
So, next time anyone goes a/b'ing, bring your ferret----before she gets her own column in an audiomag.
Rejoice! SquareBobGodPants is born! Bring the heralds, angels, trumpets, barnyard animals, etc.
