Girls night out

Two ladies went out for a girls night out, and had too many drinks. Walking back home they both needed to pee. They were walking by the graveyard and decided there wouldn't be anyone there at night and that they could do their business behind a headstone or something. The first woman had nothing to wipe with so she wiped herself with her panties, and threw them away. Her friend was peeing by a wreath and salvaged a large ribbon from it and wiped herself with it. They both finished and made their way home.
The next day the first woman's husband calls the other husband and says, "These damn girls nights out have got to stop. My wife came home last night without her panties." "That's nothing," said the other. "Mine came back with a card stuck between her ass cheeks that said, 'From all of us at Fire House #7, We'll never forget you!'
