What is sex?

An 8-year-old girl went to her dad, who was working in the yard. She asked him, "Daddy, what is sex?" The father was surprised that she would ask such a question, but decides that if she is old enough to ask the question, then she is old enough to get a straight answer. He proceeded to tell her all about the "birds and the bees." When he finished explaining, the little girl was looking at him with her mouth hanging open. The father asked her, "Why did you ask this question?" The little girl replied, "Mom told me to tell you that dinner would be ready in just a couple of secs."

Campbell water speed record

In 1964, Donald Campbell broke the world water speed record with an average speed of 276.33 mph (441.71 km/h) with his speedboat, Bluebird, on Lake Dumbleyung, Perth, Australia. Earlier the same year, in Jul 1964, he had broken the land speed record at 403.1 mph (648.72 km/h) on Lake Eyre salt flat, Australia. Together, they made him the only person to break both land and water speed records in the same year. That land speed record only stood for three months before Art Arfon, on 27 Oct 1964, achieved a land average speed of 536.71 mph (863.75 km/h) in a jet car on Bonneville Salt Flats, Utah. Campbell continued attempting yet higher speeds, but died 4 Jan 1967 when his jet-powered boat crashed on Coniston Water.«
