You now have a violent exterior

[K]

Head of suede
eyes of ruin
svelte svengali
softness gone.
Barnyard savage
tattoo your head
in drunken Latin,
Illegitimi non carborundum
message done.
A clever thug
you have
become.

[Digiwizz]

Good K, and here is a bit a bit like it ?

No excuse.

Trigonometry, algebra, calculus,
And years of puzzling on the bus
Have made me a genius at maths I'm sure.
Of course all its for is to watch TV
And play Platstation games that excite me.
Still learning I like though its no use
And for it I can think of no excuse !
