Print Screen Computer Prank

One of my favourite pranks was to use clear tape to "freeze" the ball of the old mice.
These days a simple sticker on the Mouse LED pickup works great.
Other options were to swap the PS/2 mouse and keyboard plugs.
These days another favourite when two PCs are close, is to swap the mouse and/or keyboard connectors between the PCs so that each user is moving the other users cursor.

No imagination, no cleverness. Mostly people with too much time and not enough brain to expend it on.

most of the rest, ok, I can agree.

I certainly don't want to sound like the proverbial wet blanket type of guy, but I have to wonder why I would do these things to my friends. I don't want to ever display this type of disrespect to what I consider a very fine group of folks that I know would never consider doing any of these things to me. As for the type of people that do these things the saying, "An idle mind is the devils workshop" comes into my thoughts. Those folks really need to get a life with meaningful purpose. Have a nice day!

IMHO, since you asked. Broken LT Monitor was decent. For the most part, this was a waste of time, as are a majority of TR articles now days. A rehash of pics from a recent previous article. TR is definitely on the downward side of the slope. The glory days are gone.

When my mum use that OS, she thought this something wrong with the computer, because the monitor window comes from nowhere when she login, and there's no reflection when she try to close it.
And also I hide all the ICON on the desktop, so all the icon you want to click is part of the background picture~ You can even hide the tool bar, such as hide it and drag it to the top~
