jIltob'or (classic): This is "your robot" backwards, but does anyone get how this ties in with the concept of being a classic?
{tob} "test" and {'or} "pilot" = "test pilot"? There is a classic movie (starring Clark Gable) named "Test Pilot", but I can find no connection to anyone named "Jill".
roqlIpe' (civilian): "Apple core" backwards, but how do apple cores relate to civilian life?
Probably a reference to "Apple Corps", the company established by The Beatles. One of their business ventures was "Apple Tailoring Civil and Theatrical" which made clothes for both theatrical productions and "civilians".
Selrach (ladder): Obviously "Charles" backwards, but googling didn't find the connection. Does Marc Okrand know a Charles Ladder (or Charles Latter)?
