A policeman pulled a car over...

A policeman pulled a car over and told the driver he had won $5,000 dollars in the seatbelt competition. "What are you going to do with the money?" asked the policeman.
"Well, I guess I'm going to get a drivers license," he answered.
"Oh, don't listen to him," said a woman in the passenger seat, "He's a smart aleck when he's drunk."
Then the guy in the backseat said, "I knew we wouldn't get far in a stolen car."
At that moment there was a knock from the trunk and a voice said, "Are we over the border yet?"

Marie Stopes

Died 2 Oct 1958 at age 77 (born 15 Oct 1880).Scottish scientist, educator and birth control advocate. She was awarded a doctorate at Munich, Germany, for her work on fossilised plants (1902). As a young girl she said she would spend the first 20 years of her life in science, the second 20 in social projects, and the final 20 years writing poetry - and she did just that. She made her name through her writing and campaigning on family planning services. Her work resulted in the UK's first family planning clinic in Holloway, north London, without publicity on 17 Mar 1921, offering a free service to married women. Its aim was two-fold, first to reach the poor and give them access to birth control, secondly to gather scientific data about contraception.
