Be it apostles or months of the year,
Twelve's a significant figure.
And look, there are twelve astrological signs
Western or Chinese, no bigger.
A group of twelve items, you might wish to know
Is labelled a duodecad,
With duodenary the ordinal form.
This is something I learned, for I'm sad:
You'll have heard of the duodenum, I assume
Well, it's named for its length, of... twelve inches.
And we all possess twelve pairs of cranial nerves
So I'm sure that, my argument clinches.
For twelve is essential, and special, and dear
And you know, half a day is twelve hours.
If you ask at the florist for one dozen blooms
Be sure, you'll be handed twelve flowers.
There were twelve tribes of Israel, I'm certain you know,
And the scientists here will remember
What the atomic number of magnesium is
And it it also refers to December.
A clockface has twelve numerals, isn't that great?
And the keyboard I'm using to write this
Has a wonderful row of twelve fab function keys
Though I admit I don't use them, despite this.
