The other husband says

On the way home they both need the toilet, so decide to stop at a graveyard, but they have nothing to wipe with.

The first takes off her  uses them, while the other takes a wreath and uses that.

The next day, one of their husbands calls the other and says:”No more girls nights out. My wife came home.

The other husband says:”That’s nothing. Mine came home with a card in her crack that said ‘from all of us at the fire station, we will never forget you. “
