An elderly American tourist arrived at French immigration at Paris's Charles de Gaulle Airport and began fumbling for his passport. The French official quickly grew impatient. "You have been to France before, monsieur?" he asked in an unnecessarily aggressive tone. "Yes, but it was a while back," replied the old man, still rummaging in his bag. "In that case," continued the official, "you should know to have your passport ready for inspection." "But the last time I came to France I didn't have to show my passport or any documents." "It is not possible," snorted the Frenchman. "I'm telling you, old man, you Americans always have to show your passport on arrival in la belle France." The American fixed him with an icy stare. "And I'm telling you, young man, that when I came ashore on Omaha Beach in Normandy on D-Day in 1944, there was no damned Frenchman on the beach asking to see my passport!"
