Matthew Hunt is a young fellow and Joshua Crane died many years ago, so it's possible (if you believe in the possibility) that Matthew is indeed Mr. Crane re-incarnated, come back to infiltrate this den of artistic decadence and puddle of spilled sensibilities. It's the Age of Science again; and what better guise for this Rational Mind to don than that of a Homer Simpson; my guard is already down.
Matthew - sorry for joking around. I had to drop math early on, as I had no brain for numbers and I still don't, so I can't comment of the specifics. (But if you ARE Joshua Crane, you'd better watch out - Mr. Bob Crosby has been called, and he's very smart!)
