That's funny!
Reminds me of the shop foreman at a place I worked at years ago. He was in the Engineering Dept. one day and as a joke we asked him if he understood the metric system. He said, "Screw the metric system! Let the rest of the world learn inches."
Of course he was the same guy we asked one day, "How many 'thousandths' are in an inch?"
He thought for a while and then replied, "Man, they're so small. There must be millions of 'em."
...and he was in charge of making sure all of production ran correctly!
