Q: Are there any unguided missiles?
A: There were, they were called miss. When it was realized that they failed because their name made them feel sad they hired a psychiatrist who determined that the only way to cure them was to get them married. So the Miss(es) married and became a Mrs. But the former Miss wanted to keep their own name so they became Misses, but no one liked that name, so they merged their name with that of their husband (Hitles) and became Missiles.
