Alex: "Mais où est la plage, s'il vous plaît?"

CRS: "Sous les pavés, connard!"

"Where is the beach, please?"
"Under the paving-stones, asshole!"

(Allusion to May '68 slogan, "Sous les pavés, la plage": "Under the paving-stones, the beach", allusion in its turn to the expanses of sand found beneath the paving-stones prised up to be used as missiles, er, paperweights).

(I'd like to draw this scene, but I'm not Cabu).
