An old woman, who was senile, loved boiled sweets and as it was the Second World War the boiled sweets were hard to find. One day while walking through the city she saw a line of women going into a building, being senile she thought it was a line for buying boiled sweets. She joined the line of women but it was a line for prostitutes to get checked for sexual transmitted diseases, she finally arrived at the front of the line. A doctor behind a desk asked her "Aren't you a bit old for this?" The old woman relied "Look sonny, I might not have any teeth but I can still suck 'em"
