Greetings, Peter,
Well, if you're of an age to retire, you will certainly have had a Classical education. Likewise, probably, if you retired due to independent means - just don't get me started on the politics of it, or I'll be racking up warnings like a maverick comedian. There are some things it just Will Not Do to be shooting my mouth off on the keyboard about - except on Twitter, which is like a bear-pit anyway.
That said, I love playing fast and loose with language. I especially love messing about with cliches' heads - in the book I'm writing at the moment (Think Yourself Lucky - a symphony of wisdom), I postulate that "if it quacks like a duck, waddles like a duck and swims like a duck, it's unlikely to be a steam-roller". I usually avoid cliches like the plague, however - except that one, because I love the almost fractal ironies therein. Sic transit Gloria Swanson, as they say.
And as you say, it's just a bit of fun!
Blessings
Andrew
