To add to the "superman" part of the greeting, depending on the mood, we would do a "full" greeting to the effect of "Good morning, Commander Patrol and Reconnaissance Wing 11, world's finest weapons tactics unit in the P-8A Fleet Introduction Team building aboard the master antisubmarine warfare base, Naval Air Station Jacksonville, Florida. LT XXX speaking, how may I help you superman?" Granted, always looked at the number to see who was calling before doing that.
My last boss (who has been in the Navy 30 years and is basically out of fucks) had a rotating line of bullshit collateral duties that he kept in his email signature to fuck with people who think those kind of things are important. Some of them sounded sort of legitimate until you got to the last one or so which made it obvious he was just trolling.
