LOL,
Years ago where I use to work,a guy from the night crew would use my desk and as a prank he'd join the clips in my desk like a chain,and it was so annoying when I needed just one clip, not a chain.
I finally guessed who it was,he was giggling,and we all laughed. We use to leave a snack or cigarette(not lit) in my top middle draw,so it was really a nice co-working relationship.
