Ah, the annual tradition of the April fool practical joke. The Telegraph and Mirror are featuring alleged BBC footage of flying penguins tellingly voiced by Python Terry Jones, TechCruch gets in on the act with a well constructed spoof, but Google has caught the eye with two efforts.

First up is a fake joint venture between Virgin and Google to setup the first colony on Mars, complete with a toe-curlingly awkward video from Google’s founders themselves (embeded below).

Second, is actually a pretty amusing and bold effort from YouTube who are RickRolling all of their featured videos in the UK and Australia to redirect them to Rick Astley’s cheesefest ‘Never Gonna Give You Up‘ complete with his hypnotically strange dancing.

A good day to throw off the corporate shackles and show you have a sense of humour.
