"Beware the Jabberwock, my son!
The jaws that bite, the claws that catch!
Beware the Jubjub bird, and shun
The frumious Bandersnatch.
For the "Thread Troll" is among us, and his slithy tongue does gyre and gimble in the wabe. All mimsy were the borogoves, and the mome raths outgrabe.
A troll is a person who sows discord on a thread by starting arguments or upsetting people, by posting inflammatory, extraneous, or off-topic messages with the deliberate intent of provoking readers into arguments, and disarray.
The "Troll" who wanders on this thread is easily identifiable. I will choose to regard him as "The Invisible man" henceforth.
Enjoy the music.
