EARTHWORMS! earthworms!
The rain is falling, the sidewalks are wet and warm,
and the earthworms are out on the concrete!

I can't find the silly poem I read in my childhood.
The one that started,
Rain, Wind and Rain!

In which the young (?) earthworms wanted to get above ground
and wiggle around in the rain,
and the old earthworms warned them about getting squashed.
