A policeman noticed an older woman walking along the street.She was             carrying two large bags and twenty-dollar bills were falling out of one of them.
    "Excuse me, ma'am," said the policeman, "But why are those twenty-dollar bills in the bag?"
    "Well, officer", replied the woman,"You see, I live near a park behind a tavern and when the men come out for a piss I pull out this knife and say sixty dollars or I cut off your dick."
    "Well", relied the officer, laughing,"I guess there's really no law against making money that way but what's in the other bag?"
    "They don't all pay" she answered.
