Weekly Rant-

My best office prank by far was at my high school. First, I bought a USB rubber ducky and programmed it to backdoor my friends school computer with netcat and a batch file that ran in the background so that I could connect to his computer any time inconspicuously. The next day, I injected his computer with the drive when he went to turn in some papers.
You should've seen the look on his face when his computer started having conversations with the teacher.
