Charlie Mc beat me to it about the mislocation of Lazarus's blaster. The ability to conceal a weapon was a main reason he liked wearing a kilt.

I enjoyed all his stories, especially Methusalah's Children and Time Enough for Love.

It was from Heinlien that I first learned the truth that democracies work until the masses learn that they can vote themselves circuses and ice cream. (That's not a quote; it's from memory, but it gets the pint across.)

It was a paraphrasing of an older quote and an idea sometimes attributed to Alexander Tyler, a Scottish historian of the 17th century, among others.

Like most good writers of any genre, Heinlein could present important ideas that made the reader think whether you agreed with him or not.

Yeah, I may be old, but I'm definitesly a fan! I definitely grok ole Bob.
