One summer when I was in college, Dinger got me a job beta testing computer and video games. We would come in, BS for a couple of hours, play "work" games for a few hours, dictate some bug reports, drink a bunch of soda, then play "fun" games the rest of the day. The best was when the "work" games were also fun. Most weren't, e.g. the port of Double Dragon to Atari 2600. But occasionally the work games were great, like Sim City or Military Madness.
