'Farceur' P.G. Wodehouse invented a character called Psmith

(the P being silent, as in Freud).
His novel Leave it to P..... repeats and holds up
a single 'Poetic' line (or Line Poetical)
to ridicule.
I quote it here and add another
to make a splendid Rhyming Couplet
which Pelham G. would probably
have wished to smother
- so I have changed the first word
so as to make the first three accord
with the title of my website:

Across Beyond the pale parabola of joy
I spied the penis of a pissing boy.
