The Universe (reconsidered)

Nature’s wisdom has supplied
Defenses for each creature’s pride
Stingers sting and teeth can bite
Each species must defend its right
To stop another eating him
With sting or teeth defeating him
Cause pause for thought with thought of paws
Especially with retractable claws
The skunk can stink
Octopi ink
And the vampire bat, fresh blood will drink
But the scariest thing nature created
And to our species relegated
Time has now placed on this list
Is the angry physicist.
