PS For Hikers outside of the UK, here's some info on Viz comic:

And an example of their parody of womens magazines' "top tips" page, "as sent in by readers":
Viz Top Tips: "Why waste money on expensive binoculars? Simply move closer to the object you wish to view!"

Oh well, I suppose you really had to be there...
