A famous Flann O'Brien poem:
The Workmans Friend
        
When things go wrong and will not come right, Though you do the best you can,
When life looks black as the hour of night-
A PINT OF PLAIN IS YOU ONLY MAN.

When Money's tight and is hard to get
And your horse has also ran,
When all you have is a heap of debt-
A PINT OF PLAIN IS YOUR ONLY MAN.

When health is bad and your heart feels strange,
And your face is pale and wan,
When doctors say that you need a change,
A PINT OF PLAIN IS YOUR ONLY MAN

When food is scarce and your larder bare
And no rashers grease your pan,
When hunger grows as your meals are rare-
A PINT OF PLAIN IS YOUR ONLY MAN.

In time of trouble and lousy strife,
You have still got a daring plan,
You still can turn to a brighter life-
A PINT OF PLAIN IS YOUR ONLY MAN.
