Practical physiology

Emeritus professor
Of truly world renown
An academic Mr Big
All decked in cap and gown

Speaking on the subject
Of physiology
Students flocked into the room
The big man for to see.

Deafening sound of big bass drum
(T'was no drum, but he)
Pounding t'wards the double doors
(Methinks he did need three).

Heave and squeeze and in he oozed
Seeming to take an age
The audience scarcely drew a breath
As the big man went on stage.

"You see a man standing here
Obese you might suppose
But look beneath and you will see
Not fat, just adipose."
