Bad two verse

It's Valentine's; as everyone knows
A time for poets to compose.
I'm far less romantic than any rose
So this is how my sonnet goes:

Ain't iambic pentameters curious
constructions! Scansion should not present
much difficulty but, in this event
words sound contriv'd if not plain spurious
(especially when endurious
attempts are made to rhyme). Consent
to form won't necessarily prevent
disharmony. Despite my furious
travails, it's not the metre which assails
me. Sesquipedalian form curtails
the opportunity to raise a laugh:
five feet of philology fail to fire
much comedy when witty words require
one syllable, or fewer, maybe ha-
lf?
