On their way home from a night on the town 2 girls are desperate for a wee. Lets go in the cemetary one suggests. So they go up against some gravestones.
"What are you going to wipe with?" one asks. "My knickers the other replies and then chuck them" "ooh I'm not" said the other "I've got �40 designer knickers on!" So she picks up a wreath and uses that.
The next morning one of the girls boyfriends phones the other "I think we need to keep an eye on our girlfriends mate, mine came home with no knickers on last night" he says. "I know what you mean mate," said the other "when mine turned over in bed this morning there was a card between her bum cheeks which read :
WE'LL NEVER FORGET YOU...ALL THE LADS AT THE FIRESTATION."
