What (or who?) is grey poupon? This name popped into my head and I don't know what it's from or where I've heard it. I can look up online, but I figured I'd rather ask you first.
i think it was from a famous commercial. the name of the product was "grey poupon" and the commercial i think had a british person asking another british person something like "pardon me, do you have any grey poupon?" and it still remains a pretty famous commercial even though i'm not sure anyone alive today has ever seen it. grey poupon was i suppose a brand of poupon? as for what poupon is, well that's a question i can't answer
