but seriously, poetry like this can be fun and a great learning tool since it can help expand vocabulary. I wrote an entire alphabet of poems this way, but allowed some non-start letter words to facilitate meaning and for comfort of reading.
You did well there to use only O words!
this is an excerpt from L-ish, my attempt at as many L's as possible:
to lubricate my liberty
I must locate the lenient labyrinth of law
lick and lap the latent lesbian lever
(the lottery of lascivious logicality)
My larynx
a lavender lizard
is lax
so I lavish largish levels of lager upon it
(a lotion to lull the liason)
that I may laquer to the limit
in my lacy lingerie
the lukewarm lazy limpets in
their lobster limousines
I know it's not strictly poetry, but I couldn't help thinking of that wonderful speech from V for Vendetta:
Voilà! In view, a humble vaudevillian veteran, cast vicariously as both victim and villian by the vicissitudes of Fate. This visage, no mere veneer of vanity, is a vestige of the vox populi, now vacant, vanished. However, this valorous visitation of a by-gone vexation, stands vivified and has vowed to vanquish these venal and virulent vermin vanguarding vice and vouchsafing the violently vicious and voracious violation of volition. The only verdict is vengence; a vendetta, held as a votive, not in vain, for the value and veracity of such shall one day vindicate the vigilant and the virtuous. Verily, this vichyssoise of verbiage veers most verbose, so let me simply add that it is my very good honor to meet you and you may call me V.
I don't know about anyone else, but I certainly learnt a few new words there lol
