As this article describes, April Fools was a bit of a hoot yesterday with many companies getting involved in the process.

My favourite April Fools is actually not an IT one, but from BMW, and follows on in a series of april fools they've had over the last few years. Last year the advert had a phone number which, if you called, you eventually got forwarded through to somebodies real desk phone (and a surprised voice). It certainly scared the life out of us when we called.
