I don't think anyone ever uses a ruler anymore. I sure don't, especially for its intended use. Why, just now, I used one as a back-scratcher. I've once even used one to hit a person with. And when I was 13, I measured my dick with one, but I never use it to measure anything else. That's where measuring tape comes to the rescue. 12 inches is just too fucking short for anything.
Now when a ruler is used as a straight edge, there I can see its practicality. I draw lines with a ruler/straight-edge. I draw diagrams, I draw differentiating shapes, I construct perspective portraits of skylines and city blocks, I jam up homeless people with the edge of a ruler, I make horse-noises and clippity-clop noises with my mouth, but I never find myself measuring anything with a ruler. Take that, Andy Rooney!
