Contributory Negligence

I just tripped over my dog. As he's seen plenty of insurance company tv adverts, he barked and ran straight to the treat jar for compensation. However, he was partly to blame for this incident, so I'm now faced with the difficult task of explaining to him the concept of contributory negligence, which is a bit of a nuisance because I already have a ton of stuff I need to get done today. Sigh.
