Paddy is about to go into his favourite pub,when this nun grabs his shirt,and says "drink is evil.You will be damned for ever"
Paddy replies "what are you talking about woman..have you ever drunk alcohol?"
"No I have not" replies the nun "it's evil"
"Dont talk stupid" says Paddy "I tell you what,let me buy you a drink,then if you dont like it,then you can say what you like"
"All right" says the nun "but what do woman drink?"
"Let me get you a vodka,and tonic" says Paddy.
The nun agrees,so off goes Paddy into the pub,where he walks up to the bar.He relates the story to the barman,as he orders the drinks.
"Jesus wept" replies the barman "is that annoying drunken nun still waiting outside?"
