Geoff,
I don't have a comeback for this one either (or is it neither?) But I do wish you have other friends who can send us more of this stuff.
And by the way I always wondered about those people who authored some of the most amusing and quite brilliant pieces which have been forwarded to almost everyone who has e-mail during the early days when e-mail was a novelty. (Remember?) Who were they, they were never properly recognized, I think.
