A nun was walking home one day and a drunk bumped into her while he was leaving a bar.
"Young man! Alcohol is the elixir of the Devil!" His reply, "How would you know? Why don't you try a drink and then tell me?" She considered it and then asked, "Okay, I'll take a drink, but be discreet and bring it out to me in a paper cup." He returned to the bar and ordered two drinks, one of them in a paper cup. The bartender leaned over, "Is that damned drunken nun back again?"
