Another tale about good old country boys

Just another tiny village pub
And I was hot and thirsty after a long hike
One small table and one vacant chair
So I walked over and sat down beer in hand
Opposite me sat an unkempt old man
Greasy hair hanging lank, stubble on his chin
And man did he stink
Stale sweat and ***** and unmentionable things
I couldn't help myself, said don't you ever bath
He looked at me with beady eyes
Then he began to laugh
When was the last time you was sick boy
He said to me
I said just a week ago when I had the flu
He grinned at me, showed blackened teeth
Said the answers plain to see
You shower or bath every day to keep your body clean
Now me boy never a day ill in my life
And I rarely take a bath well about one every
Six months or so
So boy the answers very clear at least it is to me
Every time you take a shower
You wash away your natural eemunity
