The other day, in the back of a cab--
Foreign-sounding cab driver: My brozher tell me dere are over two hundred thousand jobs on Vall Street. But I don't understand- ees such a small street!
Me: Oh, no, no. Wall Street just refers to all the finance jobs in New York- most of them are in fact in midtown. It's a metonymy situation.
Foreign-Sounding Cab Driver: Ha! I must tell my brozher.
