Slothman

Superman came from the planet Krypton.
He can fly to Jupiter and  be back before you knew he was gone.
Nobody on Earth can equal his might.
Nothing can hurt him except kryptonite.
His flights through space have been farther than NASA's.
He can disguise himself with a simple pair of glasses.
He can cause a hurricane with a single breath
and once he even managed to come back from death.
He can clear the tallest building in a single leap
and do all this while Slothman is still fast asleep.

Wonder Woman honed her skills early in her youth.

She finds out what she wants by using her lasso of truth.

She has all powerful bracelets of submission.

You can't defeat her. That would be a futile mission.

You can't equal her brains or her brawn.

She is the greatest of all the Amazons.

She proves that females are not the weaker gender.

See her fly though the air in all her splendor,

while Slothman, in his tree, has no intention of alighting.

He is content to let others do the fighting.

Batman is dark, moody and introspective.

He is truly the world's greatest detective.

He prowls the city from night until morning.

He lurks in shadows and strikes without warning.

While we are sleeping safely in our sheets

he is patrolling Gotham City's streets.

He'll be out there until daylight,

for, as he likes to remind us, he is the night.

He will fight supervillains as well as lowly thieves,

while Slothman is content to loaf and munch on leaves.

Then one day came a great aberration.

Something destroyed the Earth, every continent and nation

and almost everything else in creation.

There was destruction in every location.

The planet was consumed in a great conflagration

as though everyone suffered eternal damnation.

What led to this dreadful situation?

There is one clue as to its causation:

The superheroes all went on vacation

and left Slothman in charge of the Justice League's space station. - Jeff Barnes
