In the movie Wayne’s World, Wayne and his companions halt at a traffic signal, and alongside them a posh car, possibly a Rolls Royce. Wayne lowers his window, seeks attention from the neighboring car’s window, gesturing for the distinguished older gentleman inside to lower his window. Once their windows are down, Wayne inquires politely, “Pardon me, sir. Do you have any grey poupon?”
The older gentleman’s reaction was like “What are you talking about?” And then it changes to, “Oh I understand go away.”
