Here's my most recent clumsy moment, a week after it occured:
I was at a restaurant for lunch (completely sober) and was walking to the bathroom when I turned a corner and smacked my face into a pole. I started my new job 2 days later and everyone thought I was having "domestic issues." It stayed black and blue for a month.
I also tend to sprain my ankles badly. I've torn all the ligaments and tendons in them before... no more running for me!
