According to old Sigmind Freud,
Life is seldom so fully enjoied,
As in human coition
In every position
With the usual organs employed.

There was a young man named O'Rourke
 Heard babies were brought by the stork,
So he went to the  zoo
And attempted to screw
One old bird -- end-result: didn't work.

A pancy who lived in Khartoum,
Took a  lesbian up to his room
And they argued all night
Over who had the right
To do what, and with which, and to whom.

There was a young fellow of Mayence,
Who fucked his own ass - in defiance
Not only of custom
And morals, dad bust him,
But most of the known laws of science.

There was a young lady of Totten
Whose tastes grew perverted and rotten.
She cared not for steaks,
Or for pastry or cakes,
But lived upon penis *au gratin*.
