office
Me and another guy used to torment the old guy that sat next to us in the office.

Changed the 'N' and 'M' keys around on his keyboard.
We found out that at least one of these was in his password, when he had to call IT to get his password reset.
He was raging.

Also rotated his monitor display 180 degrees, then watched and laughed at his puzzled expression.

Poor old Bob

You would have thought that with a password you type every day
you'd be able to type it without looking at the keyboard.

also the simple "put Caps Lock on" works wonders too with this
...another one we've done was swap the mice around so that the person next to the target had his mouse instead (and was in on the prank). They'd watch the guy start to use the mouse and mimic his first attempts of trying to click stuff on the desktop, before checking the mouse for dirt on the ball etc. I had one guy going for about 5 minutes doing that :D
