i'm terribly amused by this exchange from paul temple and the van dyke affair. paul and steve are in paris, and paul is trying to break into a flat.

paul: *urgently* steve, you stand on guard - if you see anyone, whistle..."rule britannia."
steve: *flippantly* i'd sooner make it "c'est si bon."
paul: *crossly* i don't know "c'est si bon."
