I did read your later post, milk monitor - it depends what you mean by "joke site". I'd say it was a joke site, tied in with a joke book, written with the intention of amusing, and not necessarily too reliable. Not even intended to be read as reliable.

And that stuff about the "black bags van" is part of the same kind of spin as the stuff about "don't ask for black coffee", and the "EEC bans bananas that are bent" and so forth.
