An old man goes to France. When he lands at the airport, he’s stopped due to not having a passport.
“Since when do you need a passport to enter France?” he demands.
“You’ve always needed a passport to enter France,” they tell him.
“I didn’t last time I was here!”
“That’s not possible, they must have asked for your passport then too.”
“Well,” says the old man peevishly. “When I landed on the beach at Normandy, there weren’t any damn Frenchmen around to ask for it!”
