God bless the young'uns

There is a younger fella who works here in the office while he finishes a degree. He's a junior with no major, 20 years old. We were having a discussion about North Korea, nuclear weapons and unsecured ports. (I nearly typed insecure ports, but that would be a port with a problem) So the ex-military boss was talking about an attack, the young'un was sure we would be safe because "you can't shoot missiles from underwater."

Someone please find me intelligent kids in college, I need to be reaffirmed.
