Jag glömde det, grattis!
Under första världskriget spelade engelsmännen fotboll på krigsfälten mot tyskarna, de bjöd varandra på choklad, cigarretter osv. så då kan man väl säga grattis till Osama också.
The English brought a soccer ball from the trenches, and pretty soon a lively game ensued. How marvellously wonderful, yet how strange it was. The English officers felt the same way about it. Thus Christmas, the celebration of Love, managed to bring mortal enemies together as friends for a time.
The British accepted the invitation and offered some tobacco as a return present. That evening, at the stated time, German heads suddenly popped up and started to sing. Each number ended with a round of applause from both sides.
The Germans then asked the British to join in. At this point, one very mean-spirited Tommy shouted: 'We'd rather die than sing German.' To which a German joked aloud: 'It would kill us if you did'.

They began by placing candles on trees, then continued the celebration by singing Christmas carols, most notably Stille Nacht (Silent Night). The British troops in the trenches across from them responded by singing English carols.
The two sides continued by shouting Christmas greetings to each other. Soon thereafter, there were calls for visits across the "No Man's Land" where small gifts were exchanged — whisky, jam, cigars, chocolate, and the like.
