Never Lie To Grandma

Lulu was a prostitute. One day there was a raid.
All the prostitutes were lined up outside the police station as they
took them in one by one.
As Lulu stood in line, she saw her Grandma coming down the street and
was so ashamed, Grandma didn't know her occupation. Grandma stopped to
say hi and asked what the line was for. Lulu, saving face, said that
the police were giving away fresh oranges to those waiting.
Grandma said wonderful, she loved oranges  and got at the end of the
line. When the policeman got to the end and saw her, he was amazed.
He said, 'How the heck do you do this at your age?' She said, 'I just
take out my teeth, rip the skin back and suck 'em dry!' The policeman
fainted.
