Somewhere along the line, personal computers became the preferred target for April Fool's jokes. Some aren't so funny, like viruses and denial of service attacks. Others are mildly funny, if you have the maturity of a 12 year old boy and it's not your PC tied up for half a day while IT tries to figure out that's a fake blue screen of death.
Wired (enabling grownups who never got past age 12) has even put together a list of top ten April Fool's pranks to play on your colleague's computers.
Whatever happened to short sheeting a bed, bogus calls from angry bosses or ordering your neighbor in the cubicle next door a half dozen pizzas at lunch time?
I guess this is April Fool's 2.0.
