"Didn't Want Grandma To Know" joke
Mary was a prostitute but didn't want her grandma to know. One day, the police raided a whole group of prostitutes and the girl was amongst the group. The police lined up all the prostitutes on the street, when Mary's grandmother walked past. Along comes the grandma and sees her grand daughter.
Grandma asked Mary, "What are you lining up for."
Mary, frightened to let grandma know the truth said "Some people are passing out free oranges and I'm lining up for some."
Grandma wanted oranges too, so she went to the back of the line.
A policeman was going down the line asking for information from the prostitutes. When he got to the grandma, he was bewildered and asked, "You are so old, how do you do it?"
Grandma (thinking he's asking her about how she can eat oranges) replied, "Oh, it's easy, I just take off my dentures and suck them dry.
