STILL MORE ON THE SUBJECT OF YETIS

Yetis were created at 4:37 p.m. on the sixth day
When, if there'd been any about, a blue thread
Couldn't have been told from a green one.
(As a tailor's grandson I have a hereditary interest
In threads and spools, bobbins, spindles, needles,
And angels dancing on the heads of pins.)
If -- pray note I am too polite to say "when" --
The human race doesn't work out
Yetis are meant to come down from the mountains
And, apparently, set up small businesses
Or find work as butlers, buskers and busboys.
The Book of Yeti's text may be corrupt, though;
And this not be the plan at all.
