I've updated the pages on my site that deal with science spoofs, commercial fake sites and social, political, historical, news, religious, travel and educational spoof and fake sites. I know from the feedback that I get that these sites are well used, so I have deleted the few that no longer work and I have added some more in. There are now a total of 61 sites split between the two pages. It's not a complete listing, and it's just my personal choice, but you might be interested in them.
They're primarily designed as a teaching aid, but some of them are very amusing indeed, if you have that sort of a mind!
