Classic Poem

Oh to be One-way — yet to be said to look
" Before and after"! What bat was it mistook
The ancestral coccyx for a periscope —
Who was it handed out that two-way dope?
(Oh blast his eyes who took my tail to be
A spy-glass, or supposed my back could see.
That two-way stuff's in the worst taste. What's more
It saddened Shelley. I prefer Old Moore.)
DORSUM's our password, with six-foot of wall
Twixt us and pastness — a Humpty Dumpty fall
For little you or me, if we should use
Our backs for peeping-tomming Goodie Two Shoes
Could not be goodier than little Miss One-Way
Or Master same, vowed to the Forthright-Way.
