This is still my favorite, I loved it when I moved people into their offices.
Employee: I can't find my files on my system.
Me: Did you delete something?
Employee: No, you moved my office yesterday along with my computer. When you did that my files disappeared.
Me: What files are you looking for? Were they on the H: drive or C: drive. We did not redo your computer so everything is there.
Employee: They were in my documents (which a shared network drive). I can't find them this morning. I think they are still in my old office.
I walked away because I could feel myself about to begin a fit of laughter.
