The dolphins and tuna approaches were entertaining as well.
Interlocutor, as I reach for a can of tuna . . . "That's not dolphin-safe."
Reply: "That's ok, I'm not taking it home for my dolphin to play with."
The other one he used was the complaint that the dolphin-free tuna tasted funny.
Mind you, these are paraphrased. The man was a consummate entertainer, even though I stopped listening to the show decades ago.
"Talent on loan from God" is another one-liner he liked to rattle off. I'd like to think the peace he portrayed having with himself toward the end was not so much a peace that passeth understanding, as per Philippians 4:7, rather it came across a peace that comes from understanding, accepting the fact in the gracious manner he accepted most callers on his show, with an air of tact and diplomacy.
