An Allied pilot gets shot down over Germany and the Gestapo gets him. His leg is broken, so they have to amputate. He asks them:
“Can you please have one of your guys drop it over my base in England?”
So they do it. The next week, they have to cut off his other leg. He asks them again:
“Can you please have one of you guys drop it over my base in England?”

“Can you please drop it over my base in England”
This time they say:
“Nein! Zis ve kan’t do anymore!”
