Telephone etiquette

Love those robo calls. That lady starts right up and you hang right up. What to do with the real people?

Anyone who doesn't identify themselves immediately is automatically considered a telemarketer. I hang up on them, too, but I usually exchange a couple of words.
"How are you this evening?" "Busy." Click.
Today I came up with a response after I disconnected. "Is LohMan available?" "No." Click.
Next time: "Is LohMan available?" "He's married." Click.
