I'm not sure who (if anyone) would find this interesting, but I ran across a list of Secret Service Code Names used over the last 30 years or so. Supposedly they are all random, but you had to think someone had a sense of humor some of the time. My favorites are Barbara Bush, Amy Carter (only because of the irony there), Dick Cheney, Walter Mondale (who knew he was a monkey barner?), Barack Obama and Ronald Reagan.
You'll quickly notice they use the same letters for families. As I said, most are just words with no implied meaning to the person, but you can't tell me someone wasn't smiling, at least occasionally.
