This is the Story of Seamus O'Flanderghanagan

Seamus is famous
I’ll here tell you why
For one year ago
He spat in the eye
Of one Mayor Bishop,
A scurrilous rogue,
Who sang like a canary
But looked like a toad.
But why, do you ask
Did he spit in the eye
Of this one Mayor Bishop?
Well I’ll tell you why.
Seamus was the town drunkard
And Mayor Bishop the priest
One preferred praying
The other preferred yeast.
On this day yon year ago
Mayor Bishop did a-spy
Merry Seamus O’Flanderghanagan
Waist deep in his whiskey malt dry.
“Shame!” Cried the mayor.
“Shame on you sir!
Cease this leachery!”
At that, he caused quite a stir.
“Listen, boyo” replied the drunk
“I have a dreadful taste in my mouth
Will ya spare me some change?
I’ve a hankering for vermouth.”
What happened next?
Your guess is as good as mine.
All we know is that Seamus
Spat in Bishop’s eye.
Mayor Bishop became depressed
And took to the pub’s ale
Then took Seamus’s spot
As town’s drunkard male.
What was poor Seamus to do
But take up a trade?
With only one left
He became Mayor that day.
And still is he sitting
Perched in that office so high
Wishing to catch up
To Bishop’s whiskey malt dry.
