I need to start wearing makeup to work becuase I don't know the word No.

So I work for an advertising communication firm and sometimes our graphic designers like to use people in the office when they are a creating proof of concept for a project. I usually like to imagine myself answering these requests with a resounding NO, but as many of you know that word is not one I am very good at using. So instead I get stuck back in a warehouse in front of green screen with no make up on, looking rather chunky and I get to be immortalized into the proof of concept video they are going to send to a group of clients. WOW....I think maybe I should go on a diet. Please tell me that the camera adds 20 pounds, not just 10?
