Recently i have asked question on super user regarding one prank by my colleague and the prevention technique, And this comment made me to think on another question,what were the pranks which you played with the colleague,if i ask will it be off topic?

i thought to ask the question since it will come up with some tricky parts of windows and linux where users play around with and it will help us new stuff and prevention,will the community take it as followup question or it will be closed as off topic?
