“There are many good reasons for drinking, and one has just entered my head…”

A drinking rhyme was printed in The Berkshire Evening Eagle (Pittsfield, MA) on March 18, 1916:
   
“I know many reasons for drinking,
And one has just entered my head—
If a man can’t drink while he’s living
How in hell can he drink when he’s dead?”

 
The rhyme wasn’t printed during the Prohibition years, but was printed in The Spur (New York, NY) in slightly different form in June 1936:
   
“There are many good reasons for drinking,
One has just entered my head,
If a man doesn’t drink when he’s living
How the hell can he drink when he’s dead?”

 
The rhyme is often associated with drinking on St. Patrick’s Day.
