a few years back a "small / semi tradition" started between myself and one of my "brothers" / programmers (you may know him as Flyingwulf or just Wulf)
He had taken an offline job and hated it, so once a week myself, Mrs. Loki and Wulf's family would gather at their house and come up with something to do to Wulf when he got home, just to mess with him, make him smile, and put him in a much better mood....
These are in no particular order...
We bought nerf dart guns for everyone in the house (about 7 in total I think) most were automatics, the rest were semi's mine rapid fired with a 50 dart clip
After all the kids had their fun warring in the back yard we came back into the house and took our positions hiding with our guns all aimed at the door
When Wulf opened the door EVERYONE opened fire
couple hundred nerf foam darts, sticky darts and suction cup darts pelted him as he opened the door.
