> If my memory is correct, it comes from a television programme...
I've heard this same claim (about different expressions) not infrequently here in the forums. Expressions like this rarely come from television programs. If your memory is correct, that's the first time *YOU* heard the expression. The television script writers heard about it before you, maybe from their kids. Their kids got it from somewhere else and so on and so on.
Coming back to this particular expression, I can tell you that it was common in 1966 (among schoolkids) but had not yet hit the airwaves, as far as I can recall. Frequently vogue expressions like this one become all the rage in pop culture for a short time, but then go "out" quite quickly.
If I heard anyone say "what can I do you for" in the 80s, I would have thought they were quaint and out of touch. By the 90s it would have been painful to hear, and I would have been embarrassed for them. Any time after that, I would have wondered if they were terminally out of touch or had woken up from a coma.
Naturally, these expressions have different frequency in different parts of the planet, so reactions won't be the same everywhere.
Oh, and while we're on the topic of pop culture: there's these super neat-o vids ya just gotta see, they're the cat's pajamas daddy-o: one's a dancing baby, and the other is--you're gonna love this--little flying toasters with wings! They're baad, man!
