I think this counts as a pun, even without doing a pun-joke.
The above sent by Andréa, who particularly notes Tom Waits getting mentioned, saying “Never thought I’d see HIM in a comic – made my day!”. And one of your editors had the pleasure of taking a couple classes from Professor Lance Rips, who liked to point out that his name constitutes a complete sentence.
Meant to post this earlier.
I learned the word prodigal in the context of the Parable of the Prodigal Son, and thought it meant something like all the characteristics of the guy in the story – wandering, absent, returning after a long absence and acting all entitled, etc, all packaged in that one word. Only much later did I start seeing contexts that wouldn’t support all of that meaning, and learned the base sense spending money or resources freely and recklessly; wastefully extravagant.
And then discovered that was what it meant in the Parable, too. But there had not been enough help from the context to make that choice clear! And this fits the philosopher’s point that, if your informant points to a rabbit and says gavagai, maybe they are telling you the word means rabbit — but maybe it means finger.
