This isn't bike related, but oh well....
One day after my brother had just gotten his license he was driving me home from school and we saw a cat in a ditch close to the road. The cat gave us this scared, "don't run over me" look and just stood there frozen. My brother, being a young idiot, jokingly swerved towards the cat to scare it some more. The cat, being a dumb cat, ran into the road right in front of the car and got hit.
