A guy is walking up to a pub and is stopped outside by a nun......

"You're not going in there to drink alcohol now are you?" she says.


"Sure am." he replies.


"You know it's a sin right?"


"I'm an atheist."


"Well, what would your parents think?" she asks.


"I'm an orphan."


"Well... You know it's bad for your health right?"


"I guess? Look, what's your problem with alcohol?" he asks, "Have you ever even had a drink yourself?"


"No of course not!" she replies.


"Okay, how about this. I'll bring you out a drink, if you drink it and tell me you hate it, I won't drink for the rest of the night, yeah? So, what will you have?"


She thinks for a moment and says "Well, okay. I suppose on balance it's for the greater good. I suppose I'll have whatever ladies normally drink. Gin, I suppose? -but, could you bring it out in a cup, so I can be discrete?"


"Yeah, fine, whatever." He walks by the nun and enters the pub.

He approaches the barman and says "Can I please get a pint of bitter and a double gin, but in a cup rather than a glass please?"


The barman sighs and rolls his eyes and says "Is that fricking nun out there??"
