An overweight Wehrmacht sergeant (Gert Fröbe) delivering coffee to the bunkers sees the huge allied invasion fleet steaming off the coast of Normandy just before the bombardment opens up.
Capt. Colin Maud (Kenneth More): "Now move along! The sooner you get off this beach, the sooner the Germans will stop this blasted shelling! It's very bad for the dog!"
Another Maud one - a shell hits near him causing everyone else to hit the deck, Maud just stands there with a look of mild irritation.

A group of lost paratroopers and a German patrol run into each other in the dark and neither realizes they've met the enemy. Both groups walk past each other without concern except for the paratrooper at the end of the column who goes "Wait a second..."

"Those 5000 ships you say the Allies haven't got? WELL THEY'VE GOT THEM!"
