Random Poem Fun with words

Rain fell down hard
A deluge from above
God flushed his toilet
And let loose a flood

Some ran, some swam
some floated, some drowned
some prayed to God pleading
to please fix the plumbing

what kind of a neighbor be HE?
the neighbor from hell if you ask me
but in the end it was only a beginning
a heads up to brush up on your swimming

now there is little evidence of this flood
except for oceans, rivers, lakes, marshes
ice caps, glaciers, and tales of old
about a little boat on a mountaintop.
