The earthworms are out!
if that scientist told the truth
(earlier post on this thread),
the earthworms need oxygen and they come out when it rains.
Now they are oozing their slow and steady way
around on the sidewalk pavement,
in the puddles, while a drenching rain is falling.

Not certain if the earthworms get their oxygen
by being out of the ground,
or by searching out rainwater which is rich in oxygen, or what.
