Nice little article about work avoidance Flash gaming on Videogamer. I've only played one of these before, Nanaca Crash, which is oddly compelling; the objective being to propel a pedestrian as far as possible by smashing into them with a bicycle. My best so far is 771.88m.
Beat that, readers. (I'm sure you will.)
[Edit: Oh, it would have helped if I'd realised that you can do mid-air boosts. That's better - 2429.55m]
