I'm never going to touch a bank pen again.

Even toilet seats in public rest rooms are not especially germy. In a 1995 study, Gerba found E. coli on only one out of 59 public rest room toilet seats -- most likely from the toilet water, which aerosolizes into a microscopic mist when the toilet flushes. There were far more fecal bacteria in sinks and on sanitary napkin dispensers, the latter being commonly overlooked by janitors. (Other commonly overlooked bacterial ick zones, as determined by Gerba over the years: hotel TV remotes, vending machine buttons and bank pens.)
