Overheard in D.C.

Strictly speaking this conversation wasn't overheard in D.C., because it actually happened to me today. I was downtown near my office, crossing the street, when a car stopped, and the driver pulled down his window.

Driver: Excuse me, sir. Where's the embassy?

Me: Which embassy? There are a lot of embassies.

Driver: I don't know.

Me: Each country has its own embassy.

Driver: It has a Canadian flag on top.

Me: Oh, the Canadian embassy is . . . [I gave him directions].
