Trolls and missing appendages

Why are trolls always claiming not have appendages they actually have? Thus far, we have:

-Stacey- missing Mr. Happy

-Boxer- Missing Mr. Happy

-Snapper- This is the really weird one, considering the name, one would assume no Mr. Happy, but instead, he zigs where other trolls zag, and he’s got a missing arm.

-Ralek- Missing Mr. Springer:D

Is this phenomenon peculiar to KFO trolls, or are there other avulsed annoyances out there, typing as fast as they can without the full use of their limbs and brains?

And what kung fu technique would you use in a fight against them?:wink:
