A biker is riding along a country lane, when a sparrow flies up in front of him. The biker can't do anything and hits the sparrow. As he looks in his rear view mirror, he sees the sparrow lying in the road. Being the kind of guy he is, he stops, picks up the sparrow and takes it home and puts it in a cage, still in a coma. When the sparrow wakes up the following morning, he looks through the bars of the cage and says, "Shit, I must have killed the biker".
