A little acid from the author of Playboy of the Western World that was supposedly directed to the sister of an 'enemy' who disapproved of the play:
The Curse
by John Millington Synge
Lord, confound this surly sister,
Blight her brow with blotch and blister,
Cramp her larynx, lung, and liver,
In her guts a galling give her.
Let her live to earn her dinners
In Mountjoy with seedy sinners:
Lord, this judgment quickly bring,
And I'm your servant, J. M. Synge.
I wonder if this play's still being performed? I guess it caused quite a raucous when it premiered.
