I haven't done anything here other than bring Litterbox cake in and I think that's prank enough.

However, a few friends of mine have worked for Microsoft and some of the pranks they have pulled are hilarious.

Once while one guy was on vacation, they totally repainted his office and decorated it to look like the football team he hated the most. The rivals to his favorite team.

Another time and a different person, they filled his office full of packing peanuts all the way to the ceiling!
