Probably my favorite line in the movie:
Col. Josef ‘Pips’ Priller : [speaking in German] Thank you, my dear Hans! You have just killed both of us!
[slams down phone]
Luftwaffe major : It is getting very difficult to get any sleep around here.
Col. Josef ‘Pips’ Priller : Your prospects for a long sleep have just improved. The invasion has begun at Normandy. We are to fly there and attack with our two planes.
And the Germans boots were on the wrong feet.
