I'm a huge sports nut so I've almost always got the Espn/UFC/The Game or whatever on. Although right now it's (don't shoot me) That 70's Show that's on...oh and I like Jeopardy! a lot too.
I'll also eat (although I won't eat RIGHT at the compute, I swivel my chair away from the comp to eat....I'm messy I don't want to kill my keyboard!)
Other than that, I do like to have a few beers, although that usually ends with me waking up and going "WTH was I thinking with this city? And why am I in organized religion with no religion?" And that also leads to games that have like 60 hours played since the comp just sits there with Civ on. The comp must think I REALLY like to plan my moves out.
