Laughter Of A Clown

I am as common as the dirt  
That is swept off the floor  
Sometimes too silent  
Thought of as a bore  
 
Six feet I stand  
Not towering over all  
Though fortunately not so clumsy  
To be taking a fall  
 
Never been told that I am  
Hard on the eyes  
On the other hand not claiming  
That I have bedroom eyes  
 
Once much younger a marathon    
I did like a masochist run  
But as for running that long  
I am forever done  
 
Without a doubt something is missing  
From days gone by  
A full head of hair  
Transplants I will not try  
 
Pulling open a container  
That requires nails long  
Don't look here  
Fear of playing the guitar wrong  
 
Maybe my best asset  
Is being able to poke fun at me  
Can readily laugh  
At what in the mirror I see!
