Three women walk in and sit down at the bar. Two are in street clothes, modest attire. The third is in nun’s clothing.
Bartender asks them what they are having.
The two in street clothes say, “Boilermakers.”
The nun says, “Water.”
After the third round of drinks, when the other two women start getting loud and sloppy, the bartender asks the nun why she is hanging out with these two lushes.
“They are nuns, too,” she says calmly, “They have just gotten out of the habit.”
