Deborah, please remove yourself from my manvironment... your making me uneasy. I can't concentrate on my videogames while you're talking.

Gina, it should be illegal that I have to share an office with you. All of your personal and emotional issues that you bring to work is slowly eroding the atmosphere of my manvironment.
