I grew up in England; the only form of the expression that I ever heard used was "Coming down the pipe". Upon moving to the USA I have been intrigued by the use of "Coming down the pike", which is much more common than "pipé". Is "pipe" really just a mistake? or is there another wholly separate origin. Can someone clarify this?
