Rob’s miscellaneous activities at work?

Rob’s miscellaneous activities at work? I know what you all are thinking, but remember, he’s at the office. He doesn’t have nearly the kind of freedom for, uh, stimulating diversions as some people have. What could he be doing in that 15% of the day that he claims he’s not surfing? Making crank phone calls? Reading tea leaves? Staring, slack-jawed, at the wall above his monitor?
