When you think of common names, you think of "John Smith." Actually John has been the most common first name, Smith the most common last name, but the most common combination in the US has been "Robert Johnson." Unfortunately one of those RJ's is a known or suspected terrorist, so all Robert Johnsons are on the "No-Fly List" and will get hassled every time they fly. Even if they're babies.

Terraplane Blues, indeed.
