Many years ago Coopers & Lybrand (now PwC) was simply called Cooper Brothers. They were originally based in Gutter Lane, London. Indeed they may have been the only building with an address identified as being in Gutter Lane.
Legend has it that at one stage the partners wrote to the Corporation of London suggesting that in view of their long tenancy it might be appropriate to rename the place Coopers Lane. The Corporation, so the story goes, wrote back saying "as we've been here longer why don't you change your name to Gutter Brothers."
Post script: When, much more recently, the Corporation was selling off at auction the old City street signs, Coopers bought the Gutter Lane set.
