Tyles! Tyles! Small and bright,
That cover bathroom floors at night.
Having my nocturnal wee,
I contemplate thy symmetry.
Each small tyle, he is a square.
Beside another, they're a pair.
But try to count him, one by one,
He'll trick you, this dread polygon.
Long I sit on toilet white,
Counting tyles through the night.
Nine squares, you know, are three by three,
And thus the tyles go multiply.
Though I count them one and all,
When they fetch against the wall,
The units of this bathroom graph
Are broken by the wall in half.
Thus my count, it baffled be.
This, the bane of midnight wee.
She who the tyles doth contemplate
Will thus be left disconsolate.
