From one of my favorite on-line poets:
I was cleaning out my basement (it was overdue and more!)
And I found a couple items I'd forgotten what are for
Here, for instance, is a whatsit with a deally on its side
And I think it had a charger once, or maybe that one died
I don't know if I need it, though I really rather doubt,
But it looks like it's important, so I dare not throw it out.

The rest of it is at:
