Jack and Diet coke.

I had those our fantasy football draft night instead of beer. Or Captain and diet if you don't like Jack.

I sometimes find someone elses papers on my desk when I have off at work. Unless they have a name on them -they are trash. Tuff shit.

I keep my stuff neat and organized so I know right away if it's messed with and my chair is set at the tallest position. Usually the lever that looks like a paddle lowers it/raises it. If you were serious about that. I would stick something gross on the lever next time you are not there so the person messing with it gets a handful of well....whatever. (just remember to use a tissue to lower it again)
