I've kicked my coffee table countless times and I never learn. I always take my anger out on the table as well, as if it's the table's fault.
I once did that. Not a coffee table, but a chair. Goodness knows how I missed seeing it, but I swung my leg in frustration and practically ripped my big toenail off in the impact. It was very late, so I drank an awful lot of alcohol very quickly, used a modelling scalpel, with a fresh blade, put my big toe under the cold tap and performed the surgery. These years later you'd never know which big toe got damaged. Did I have a hangover the next day though. Ooh..! Took about a month to fully recover.
