There's a line from the first Matrix movie, the only really good one out of the trilogy, where Morpheus says earnestly to Neo ... fate, it seems, is not without a sense of irony. It's time to add a corollary to this quote, along the lines of web geeks, it seems, are not without a sense of humour.

Last year, it was the web geeks who run the web servers for Yelp and Last.fm sticking Asimov's Three Laws of Robotics into their respective site's robots.txt file. Sadly, it looks like Yelp's robots.txt is now unfunny and businesslike, but Last.fm's subversion of this file is still there.
