We had a guy in my former office that warrented constant pranks. Mainly bc he was such a deek hole to everyone and would flip out if anyone played a joke on him. Anyway, we had endless episodes with this guy. This one was my favorite. He was such a grinch, we brought christmas to his cubicle. Our network admin even set up his log on sound to "your a mean one, mr grinch" We even hid a camera and video taped him coming in, freaking out and ripping the lights down. Classic! The president of the company used to egg us on all the time too. However after many pranks he had to step in and stop us as he was afraid that the company was going to get sued for harrassment. 😀
