Can't you see a subtext right in front of you? Thiu cleverly inserted a poem in what only looked like an attack on Trim.
Thiudareiks Gunthigg: A Poem Describing Myself.
Crazed ranter
crawled out from whatever sewer
hiding
waving his arms around and howling
again clearly embarrassed
marginal creature of the gutter
baseless and undignified
this crackpot
this funny little pleb
this wild-eyed vagrant
cowardice
scuttling back to his stinking garret
I this creature
nailed to a doorway in an abandoned alleyway
no class and no clues
the Sewer-dweller
wheedling and whining
slink away like a *nithing*
I'm a Thiudareiks Gunthigg / Theodoricus Flavius
