The Mighty Thor

The demon, Mephisto, is using his magic to turn the good and righteous men into bad and indecent fools;

Those bad and indecent men are having their pants sag off their behinds and that isn't cool.

When Dr. Donald Blake hears the news of what Mephisto is doing, Blake morphs into the mighty Thor, which is great;

Mephisto is one of the supervillains that Thor hates.

When Thor finds Mephisto, the Asgardian and the demon battle each other, which is true;

Defeating Mephisto with his hammer and fighting techniques is what Thor would do.

Thor makes Mephisto turn the bad and indecent fools back into good and righteous men, as you can see;

They're no longer having their pants sag off their behinds and I'm speaking honestly.

The defeated Mephisto vanishes and here's something else that I'll say;

The mighty Thor has saved the day.
