I was looking through this site Risdall Marketing Pie Blog Archive Google’s April Fools Sense of Humor and it lists the april fools joke played by major companies such as Microsoft, youtube, google and such.

On youtube, all the videos on the home page went to Rick Astley-Never Gonna give you up music video lol.

The one by Microsoft, Microsoft's $1 Million Guarantee Program To Win Searchers was also a very good one!

Did anyone else notice these changes?
