Origins

The origin of this unit is a matter of some debate on the web. My first exposure to it: National Lampoon, March 1974 in the article "Stupid Aptitude Test" had: The Star Epsilon Eridani is 174 light years from Earth. A spaceship leaves earth and reaches Epsilon Eridani in 98.4 years. What is the speed of the spaceship in furlongs per fortnight?
