An American pilot who had downed a German Messerschmidt, visited the German pilot in the field hospital. Finding the fellow in pretty bad shape, the American asked if he could do anything for him.
The Nazi admitted that he did have a favour to ask. The leg they amputated, on your next bombing run, could you drop it over Germany?

Sure, pal.

It was a pretty weird request, but the pilot was happy to oblige and came back to tell him the mission had been carried out.

The grateful German gasped his thanks, and another request. The other leg got very bad, they had to cut it off. Could this, too, be dropped over my homeland? It would mean a great deal to me.

The American shrugged, but returned two days later with the news that the job was done.

Many thanks, whispered the downed Nazi, now ashen faced and unable to lift his head from the pillow. I have just one final request. Last night they had to amputate my right arm…

Now hang on just a darn minute, interrupted the American angrily. Are you trying to escape?
