Both were very faithful and loving wives, however they had gotten over-enthusiastic on the Bacardi Breezers.
Incredibly drunk and walking home, they needed to pee. So they decided to stop in a nearby cemetery.
Having nothing to wipe with, one of them thought she would take off her panties and use them.
Her friend however was wearing a rather expensive pair of panties and did not want to ruin them, but was lucky enough to squat down next to a grave that had a wreath with a ribbon on it, so she proceeded to wipe with that.
After the girls did their business they proceeded to go home. The next day one of the women's husbands was concerned that his normally sweet and innocent wife was still in bed hung over, so he phoned the other husband and said, "These damn girl's nights out have got to stop. I'm starting to suspect the worst. My wife came home with no panties!"
"That's nothing", said the other husband, "Mine came back with a card stuck between her butt cheeks said: "From all of us at the Fire Station... We'll never forget you."
