But let's stick to the workplace.
All of you may have come across some nasty personalities at your job.
it is either a:
evil boss ::::: a**kissing servants :::: rude secretary :::: or sometimes all 3 combined.
So, this are the kind of victims that deserve it.
IT'S TIME FOR REVENGE, the prank that will let them know they are not liked at all >:)
Remember, watch your timing and be quick. Do some practice first, test how fast you can operate it.
(!): I saw after publishing a similar instructable about this, yet I took this prank to another level, it's more about confusing, not making the victims believe they computer totally froze up. They won't suspect it is prank. Read the end of the instructable also, please.

What if they couldn't click any more, but still can? This is as confusing as it gets :D
One typical Windows XP desktop, ready to be hijacked :D
