Wrong Choice 3A

Luke Ratla was an old human from the first days of space travel. he was one of the first people to meet Klingons face to face. When they said nuQ neH to him, he thought they said "Nuke Neck" and clearly thought it meant that you should attack their neck. .. you know, like a nuclear assault. So he did. And now you know why Humans and Klingons have been at each others throats for so many years.
