Lint

There are things in life that are
Mysterious to me.
Maybe they'd be clearer
If I had a PhD.

One involves the laundry
So I'll give a little hint -
Won't someone explain to me
The origin of lint?

Clothes come from the washer
And the dryer claims them next.
Nothing's hanging off of them,
So I am quite perplexed.

For when they're done, I clean the trap
Where lint is piled up high.
That stuff has somehow formed
Between the wet stage and the dry.

If there's a person out there
With an answer to my query,
I think that explanation may
Just rival Einstein's theory!
