Arthur was sitting outside his local pub one day, enjoying a quiet pint and generally feeling good about himself, when a nun suddenly appears at his table and starts decrying the evils of drink.

You should be ashamed of yourself young man! Drinking is a Sin! Alcohol is the blood of the devil!

Now Arthur gets pretty annoyed about this, and goes on the offensive.

How do *you* know, Sister?

My Mother Superior told me so

But have you ever had a drink yourself? How can you be sure that what you are saying is right?

Dont be ridiculous – of course I have never taken alcohol myself

Then let me buy you a drink – if you still believe afterwards that it is evil I will give up drink for life

How could I, a Nun, sit outside this public house drinking?!

Ill get the barman to put it in a teacup for you, them no-one will know

The Nun reluctantly agrees, so Arthur goes inside to the bar.

Another pint for me, and a triple vodka on the rocks, then he lowers his voice and says to the barman … and could you put the vodka in a teacup?

Oh no! Its not that drunken Nun again is it?
