Once upon a time, far away some place,

Two princes got up in each other's face.
Sir John hated Sir Ron and so he vowed,
And promised to fight him till he was in the ground.
Sir Ron, in turn, loathed Sir John,
Hated him like Eminem hates his mom.
They were treacherous, neither one could be trusted,
Ron would give you hot dogs and steal the mustard.
That provoked, brought about a response from John,
Who hit Ron's arm hard like a ping-pong ball.
Ron retaliated, got back at him fast,
Broke his arm, now Sir John's wearing a cast.
But this wasn't the last; there were subsequent fights,
More that came after, so for hundreds of nights,
There was a siege on Ron's castle,
John surrounded it, and attacked it from every angle.

I've seen fire, and I've seen rain,
I've seen joy and I've seen pain,
But it seems to me, there just might be a way…

Now this is fishy like halibut, a trick that was elaborate,
Worked out with great care and detail.
John rolled a rock to collide with Ron's car,
Hit the side and hoped he died.
But Ron found sanctuary in a sanctuary,
Found safety in a holy room, you know me? Good.
Then Ron decided to do the same thing,
He launched a series of operations, a campaign.
Then he did something severe and drastic,
Launched bombs to attack, John launched bombs back.
They didn't think about the effect or consequence
Of their actions, so guess what happened?
The end seems inevitable, sure to occur,
Ron and John both died, but why?
Before you find yourself in this kind of predicament,
This bad situation, you better think on it…

I've seen fire, and I've seen rain,
I've seen joy and I've seen pain,
But it seems to me, there just might be a way…
