Over or under
Apparently, how you roll your toilet paper says something about your personality. (Click for full graphic.) Engineering Degree

The folks at Engineering Degree have taken a scientific approach to answering one of the most critical questions of modern times--should toilet paper hang over or under? Check out their detailed infographic above, complete with Jay Leno's take on the issue and scientific equations to impress your postmodern nerd friends.

The in-depth look into the advantages and disadvantages of each toilet paper orientation was created as part of a viral marketing campaign for Engineering Degree, a resource for would-be engineers.

My personal take--if you really want to get good coverage in the trees and on the roof, it's essential to throw the roll with the paper hanging over. So, which way do you roll?
