I’ve seen my share of office pranks: filling an office floor to ceiling with packing peanuts, cover over the doorway to someone’s office, moving an entire office, fully functional, into the building lobby… the list goes on.

But some of these I’ve never seen before. Good fodder if you’ve got a co-worker about to go on vacation.

(Hint: its always easier to get a group of people to pull things like this off. Order a pizza, bring some beer, and you’ll be surprised what you can do in an afternoon).

With some careful searching you can find even more photos of creative pranks.
