Who's What?

Girls and boys, come out to play —
Which is which I cannot say.
For we’ve lost,
But lately, these:
Waist and bust
And pretty knees.
Nothing helpful ever shows
Under jeans and sloppy joes.
Sir, no doubt — or is it Madam?
Eve, perhaps — or maybe Adam?
Puer, I think — or could be puella? Is it girl — or shaggy fella? Better get it straightened out Ere you ask a form for dances: Courts are much concerned about Homosexual advances.
