Fluffed

Does anyone really know
How the stuff that we call fluff
Gets in my belly-button?

It seems to gather in the day
And at night, while I'm away
Asleep, it makes its journey.

Such a sojourn shouldn't happen
Logic unravelled, fluff travelled
To my blow-hole.

Why does it gravitate?
And will it just once abate?
I have sat and sat to fathom.

Some people think me rude
But I do not watch my crotch,
I'm just gazing at my navel.

So next time you clean it out,
With your finger in the spout,
Stop and think of me.
