Young man: Can you tell me how to get to Carnegie Hall?
Older man: Well, if you’re coming from downtown, you should take Madison Avenue up to 57th and hang a left. Oh, you could take Fifth, but it bogs down in the thirties and forties. If you’re coming from the Upper West Side, you can take Broadway down to 57th if you’re comfortable with Columbus Circle, or you can take Ninth Avenue down if you want a stoplight….
You know, even now that I’ve been to New York City, I still don’t get the joke.
