If Sir Mix-A-Lot was an ass connoisseur, the entire Japanese toilet manufacturing industry must be ass artistes, masters, professionals, virtuosos, and wizards. If you're at all interested in how your rear is treated before, during, and after doing your business (this is how they justified the article), check out BusinessWeek's feature gallery on Japanese toilet.

Among the notable is a revolving toilet for a stroke patient, a $5000 toilet that lets users analyze their health using urine samples, a beauty toilet that minimizes splash-back, and a toilet that has LEDs and a quiet 55db flush. We can't decide which is #1 and which is #2. – Jason Chen
