A glass of wine is a fine thing,
Unless the wine is bad.
A pint of plain porter is a fair thing,
Unless it isn't very nice.
A smidgeon of whisky is a grand thing,
Unless the whisky is sub-standard.
A glass of ale is a proper thing,
Unless the ale is too warm.
A little gin is an excellent thing,
I have never observed an exception to this rule.
This is a grand one for men of the cloth.
