Lehrer's explanatory note contrasts conventional compliments with an anthropologist's descriptive vocabulary. The narrator turns that vocabulary into an affectionate catalogue of physical characteristics. All four lyric blocks are retained, including their demanding compound descriptions. These are historical comic lyrics, not a scientific classification guide; the separate author's explanation stays outside the verse.
Let me tell you of
The mammal that I love,
She's lovely, she's charming, she's divine.
That ectomorphic, hypsicranial, rufipilous, leptorrhinian
Metriocephalic gal of mine.
Oh, the touch is grand
Of her pentadactyl hand,
She's my mesoprosopic valentine.
That eurypellic, orthorachic, brachydontic, stenomeric,
Dolichocnemic leptosome of mine.
Though you might wish this chordate
Instead of mine were your date,
You haven't got a chance, its plain to see,
For nothing is more alien
To this marvelous mammalian
Than affection shown to anyone but me.
Oh, her eyes are blue
(And they're oxybleptic too),
She's endothermic, and that suits me fine.
That eurypellic, orthorachic, brachydontic, stenomeric,
Bathycolpian, leiodermatous, callipygian, platyhieric,
Ectomorphic, rufipilous, leptorrhinian
Metriocephalic little gal of mine.
