Kang-Zhi-Ba There are many different kinds of superheroes: some fight bank robbers, others fight supervillains, and somewhere at the lower end of the hierarchy, this Iron Man knock-off fights urinary tract infections in a commercial that's running in China. It's a messy job, sure, but someone has to do it: (view the video on YouKu here) The commercial was commissioned by Chinese drug brand Kang Zhi Ba to promote Norfloxacin, a capsule used to treat things like prostatitis, gonorrhea, urinary tract infections, and with this bizarrely entertaining commercial, also treats early-morning boredom.
