Knuckles Bleeding

I typically don't write poetry but this idea sprang into my mind after seeing a mistake on a computer screen at work.  Of course, after examining this poem further I keep thinking of Sonic The Hedgehog and his pal Knuckles (video game reference for those who don't know what I'm talking about).  This is not about a video game duo.  It's loosely based on a fight I got into back in middle school.  Enjoy!

Knuckles, knuckles bleeding
"You should see the other guy"
A school yard fight turned bloody
A man asks "Are you ok?"

The bullies ran away
When the sedan pulled up
He stood there in a daze
Wondering how this came to be

Walking home with friends
Trumpet case in hand
Three kids yelled at them
"Nerds, dork, fags"

His two friends fled
He stood his ground
The first punch thrown
But he chose to stay

The first kid goes down
From a roundhouse punch
The second makes a retreat
The third grabs a 2x4

Distracted for a moment
He felt a blow to the back
Whirling around
He sees the wooden plank

Using his trumpet case
Like a warrior's shield
He blocks the next blow
As the sedan pulls up

"Hey" the balding man cried
The bullies running away
He stands his ground
Looking around in a daze

"Are you okay?"
He does not respond
Walking down the road
His knuckles bleeding
