The Dragon's Mistake

In a far mystic land, like any story starts
A dragon slayer resided, and dragons of course

A princess trapped, but she was quite brave
She thought she'd fight the dragon, right to her grave
She screeched and she yelled, threw thorns at it
The dragon went mental, wondering what got her ill

He decided he'd had enough, wanted to fly her out of there
But then came her counterpart, worse than he'd imagined
The princess he kept aside, he had to save his own life
Tried to speak and put forth some sense, so he could survive

But out came a flame, oops he'd done the wrong thing
The dragon slayer wielded his sword, quite offended
And now cause of that small bit of fire, and mistaken offense
The dragon lies there, fighting for his head

We all know how the story really does end
The dragon with a spear through his heart
But all he was trying to do
Was leave the stupid humans and never come back

He never should've bothered trying to protect the princess
The ungrateful blonde, she'd have his head
