After seeing his "man cave", reading his well penned thoughts and knowing that he is a member of the bar, I would bet he can tell you exactly how many pipes he has. I suspect he has the material available so as to be able to tell you the date purchased, the vendor, exact amount of loonies spent, etc. Further, I would bet he has a chart which shows the location of each pipe (cabinet, shelf, row, and position), the date and time it is to be smoked next along with what jacket and cap to wear.
Nor, I would not be surprised to learn that he has a matrix which shows which tobaccos are to smoked in which pipes depending on the moon phase.
