""I'm verry sorry to inform you, but vee haff had to amputate your left leg,"" says the officer. ""Oh no,"" cries the pilot, ""lost a limb? This is terrible news. Crutches for the rest of my life and all that. Listen, could you boys do me a favor? Could you drop my leg over my base, so it can receive an American burial?"" The German confers with his peers and answers, ""Ziss vee can do."" A week later, the American awakens to find the officer standing over him again. ""Unfortunately, zee infection has spread, and vee must take your uzza leg."" ""No! Crikey! I'll have to get a little cart, and sell pencils in front of the library. Listen; can you boys drop my leg over my base, so it can receive an American burial?"" Again, the German speaks to his fellows. ""Ziss vee can do.""
