Lulu was a prostitute, but she didn't want her grandma to know. One day, the
>police raided a sex party at a hotel and arrested a whole group of
>prostitutes, Lulu among them. The police took them outside and had all the
>prostitutes line up along the driveway when suddenly, Lulu's grandma came by
>and saw her granddaughter standing in line.
>
>Grandma asked, "Why are you standing in line here, dear?"
>
>Not willing to let her grandmother know the truth, Lulu told her grandmother
>that the policemen were there passing out free oranges and she was just
>lining up for some.
>
>"Why, that's awfully nice of them. I think I'll get some for myself", and
>she proceeded to the back of the line.
>
>A policeman was going down the line asking for information from all of the
>prostitutes. When he got to Grandma, he was bewildered and exclaimed, "Wow,
>still going at it at your age? How do you do it?"
>
>Grandma replied, "Oh, it's easy, dear. I just take my dentures out, rip the
>skin back and suck them dry."

>The policeman fainted.
