An old biker rumbles up to a convenience store at about 2:30 in the morning.  He walks by the cashier bitching to himself about getting woke up and having to pick up tampons at this god forsaken hour.  The old biker disappears down the center aisle and reappears a few minutes later carrying a bag of cotton balls and a roll of string.  The cashier having heard his grumbling starts to ring him up and says, "I know it's none of my business, but I overheard you talking about tampons when you came in, they are about half way down isle 2 if you missed them."  The old biker stares at him a moment and replies, "Well, last week I sent my ol' lady out for some smokes and she came back with ziz zags and tobacco, by God, that fucking bitch can roll her own too."
