The billiard sharp who any one catches,
His doom's extremely hard
He's made to dwell
In a dungeon cell
On a spot that's always barred.
And there he plays extravagant matches
In fitless finger-stalls
On a cloth untrue
With a twisted cue
And elliptical billiard balls!

Sullivan (The
Mikado: The
More Humane
