Google is too useful for it's own good some times. I mean, you can actually get valid data with a query like this:
http://www.google.com/search?q=c+in+smoots+per+fortnight
For extra fun, look up Smoot (both the unit of measurement, and the person.) The irony of his story is amazing.
Yeah I really have nothing else to say about the guy/ measurment. That is pretty ironic...yeah nothing to add, I just find it funny.
*L* I have a friend named Smout, but people frequently pronounce his name as Smoot. He's in physics, so maybe he'll appreciate his mispronounced name more?

Nice!
