We've got news for you, London: you stink. And we're not just talking about the dubious odours on the Underground. On-demand laundry service ZipJet surveyed 1,000 people and found that 40 percent of Londoners admit to having worn the same pair of pants for three days or more, compared to 26 percent in the north east, 16 percent in the north west and just four percent of those squeaky clean folks in the east Midlands. And it's not just Londoners' pants that could do with a good scrub, as the survey also revealed that 37 percent of people in London don't bother to wash their sheets after a one-night stand. Come on guys, splash out on some Daz every once in a while, ya filthy animals.
