By the company he chooses

My Mom had a great memory for poetry. This segment of an Irish poem was one of her favorites which she often quoted:

It was a year ago, September,

A day I well remember.
I was walking up and down
In drunken pride.
When my knees began to flutter
And I fell down in the gutter
And a pig came by and lay down by my side.

As I lay there in the gutter
Thinking thoughts I could not utter,
I thought I heard a passing lady say,
"You can tell a man who boozes
by the company he chooses..."
And the pig got up 

And slowly walked away.
