Mrs. Giggles is reformed! Only love and cuddles from here on out. http://mrsgiggles.com/
Fluffy Bunny Lovin. Yeah, baby. Best April Fools Joke Ever? (Well, maybe not ever but definitely on the list.) Hysterical. LOL. Happy April, y'all.
And if that one didn't do it for you, how about the Guardian Goes Twitter? http://www.guardian.co.uk/media/2009/apr/01/guardian-twitter-media-technology
Or Dear Author's New Literary Venture? http://dearauthor.com/wordpress/2009/04/01/big-changes-to-dear-author-goodbye-for-now/
Or maybe CADIE's love for Pandas? http://www.google.com/intl/en/landing/cadie/index.html
April Fool's jokes may be the best use of the internet to date. You know, aside from all that "globalization" nonsense.
