A wonderful race are the Persians,
They have such peculiar diversions.
   They make love all day
   In the usual way.
And save up the nights for perversions.

and by the famous poet, lecturer and critic, John Ciardi:

There was a young lady who wouldn't.
Her mother had told her she shouldn't.
   When dear mama died,
   She felt free, so she tried,
But by then she was so old she couldn't

There was a young lady of Mass.
Rather lacking, we all thought, in class.
   She would stroll Boston Common
   And whenever she saw men
She'd whimper, "Please, sir, make a pass."
