I am looking for a safe office prank that does not take too many supplies and is only intended as a joke?

Its a plot against my boss and I dont want to get fired. He would appreciate a good prank as long as it isnt offensive.

Steal something from him! I just watched "Lars and the Real Girl" yesterday, and it was so funny because the girl kept taking the guy's action figures from his cubicle. Then she hid them and subtly put them back in his cubicle one at a time when he wasn't looking. Then he stole her teddy bear and put it in a noose. Hahaha!
It depends on what your boss' personality is..you can try something as simple as a whoopy cushion or you could get more complicated. Have fun!
to find out a few good pranks check out some Nebraska office pranks, such as: 'Golf' http://www.youtube.com/watch?v=BGR-lLFjhgs 'Raft' http://www.youtube.com/watch?v=GWrayXMTm2w 'Bird' http://www.youtube.com/watch?v=YAyJYryhIXU however, these may go a little too far (but not much)
Another good resource is the new book that just came out full of office pranks from the simple joke to the elaborate set up. Cubicle Warfare / 101 office pranks and tricks. The book is fully illustrated !! I like the Dark Coffee BB's. you glue a false bottom onto a paper cup then remove the real bottom. fill it up with small BB's and place it infront of your mark's keyboard. This video shows the step-by-step ... http://www.youtube.com/watch?v=TyrD7sXmIvk
