Creepy conductor

I was on the Metra the other day, and the conductor was walking by and saw my knee brace, so he stopped and asked what happened...so I explained about how I fell, broke kneecap, etc.

And he said, "You know it amazes me how easy it is to break a kneecap. All you need to do is hit it just so, you know--right along here (showing me the side of his leg)--and pop...the person can't walk."

Then he smiled and took my ticket.
