Sorry, misquoted you. You didn't say "all the world knows". You said "that they do this is well known to everyone and anyone who has any knowledge at all" (I knew a bloke down the pub who was so knowledgeable about 501 that he could do the maths in a split second, but who was as thick as pigshit when it came to anything else). Actually, what you said was worse. However, they're both prime examples of weasel words (do look it up on wiki), so well done.
