alt Hacker NewsThere's an episode [0] [1] in a famous Canadian comedy that makes fun of this distinction:
> Brent: Ah, the tax man.
> Drey: A tax man.
> Brent: Pardon?
> Drey: I'm not the tax man, I'm a tax man. Saying the tax man is just a little dehumanizing, thank you very much.
[…]
> Brent: A tax man. And whatever you, don't call him "the tax man." Call him "a tax man" or he kinda goes squirrelly on ya.
> Wanda: Some people are sensitive about article use.
> Brent: About what?
> Wanda: Proper article use. "A" or "an" are indefinite articles. "The" is a definite article. In fact, some people say "the" is "the" definite article.

> Hank: I know what I'm doing. We get the tax man...
> Brent: A tax man.
> Wanda: Actually, in this case you can say "the" tax man, because you're referring to a particular person.
