So, my co-worker and I have this "prank" that we do. It all started when he walked by my desk, picked a dead leaf off my plant and threw it at me. It has since become a hide the dead leaf game. When we come across a dead leaf on one of the plants, we will hide it somewhere on the other persons desk and see how long it takes the other person to find it.
Well now he has made a change. When I was out to lunch on Monday, he cut out a small picture of Napoleon Dynamite (Who he knows I positively can not stand. I HATED that movie) and attached it to a picture of hubby and me. It has taken me 5 days to notice. The entire office knew about this and it took me 5 whole days to notice! Napoleon kinda blended into the background. It was nicely done, he looked like he was there in the restaurant with us.
Now, Im not too good at these prank things and I need some ideas to get him back. Of course they have to be "office appropriate" so I dont get fired. Just something to keep fun going.
