The socialite
Not admin or techy or really bad, but interesting.
At my old job we handled short customer requests all day through computers. If the work was slow, many of the other employees would <strike>waste time</strike> abuse company time/internet browsing the web while we were supposed to sit idle and keep our eyes open for new requests.
One day, one of the annoying girls in the back left for lunch, but left her Facebook profile logged in and open. A team-lead along with a few others proceeded to update her status to notify all of her friends about how much she loved her job and would never waste company time.
