"Lock the doors and close the blinds -- we're going for a ride..."

It sucks that April Fool's Day this year falls on a Sunday.  The interruption to the normal workday usually works so much better than the interruption of a weekend.

But for those of you who want to play a prank on a loved one, a friend or a co-worker nonetheless -- here's your chance to do so.  It doesn't do any permanent damage and is a bit superficial, but it's fun nonetheless.

Requirements:  The person must have (a) a computer running Windows NT. 98, 2000, 2003 or XP (I don't know if Vista works); and (b) his/her screen left open so you aren't shut out without a password.

Go here:  http://www.microsoft.com/technet/sysinternals/Miscellaneous/BlueScreen.mspx -- Yes, it's the real Microsoft website.  Download the "BlueScreen Screen Saver."  Follow the instructions as to where you should put it per the operating system. Then -- change the person's screen saver to this one.

From that point? Watch the fun begin.
