If you'll visit Keetha's blog and do a bit of scrolling you'll discover that she, as a certified science geek, has conducted a completely unbiased (cough) scientific survey on whether toilet paper should come off the top of the roll or down behind. Her survey raised some very strong opposing opinions in her readership, but Keetha herself managed to stay completely detached and unemotional.
Or maybe not...See? She wrote about it here. And here and here and (so far) HERE. On vacation.
Science geeks. Sheesh!
