Blooppers from the previous 999 videos
A retrospective of the EEVBlog history is what I suggest. But don't overlook when #1000 is uploaded it will still only be the 998th formally numbered EEVBlog video. Assigning high significance to #nnn video numbers can be problematic.
#666 was skipped , possibly as a concession to a significant proportion of the US audience from using that religiously sensitive number. An unusual move for an acknowledged atheist to make. But it passed largely without incident so it might have been a wise move in hindsight. People with bibles and guns need careful consideration. I have vague recollections there were other factors at play too but it was quite some time ago, so I may be completely wrong in my memory of the time.
#741 was also skipped. Possibly that was to prevent Internet search issues with an Australian brothel in Melbourne called club741. A move which if true shows considerable foresight. If somebody accidentally clicked on the wrong link they may have been unexpectedly better informed. Or if their web browsing history on a work network was examined it may have led to awkward questions.
I'll give you a pass, and if Dave had the same reasoning, him too because neither of you live in the US, but nobody gives a shit about the number 666 here. Nobody would lose their minds, and nobody would really care. If anything it would be a joke, and people would have a laugh.
I agree with the consensus that Americans are fat, gun-slinging idiots, but give us some credit, we aren't gonna go nuts over a stupid number.
