A brit pilot is shot down over Germany and is sent to a POW camp. When he arrives he asks the commandant for a favor. He wants to let his family know he is still alive so he asks that one of his legs be cut off and dropped over Britain in a bombing.
The German considers it odd but honors the request. A few months later he asks again for the same favor with his other leg. The commandant again honors the odd request. A few months go by and the pilot asks if he can now have one of his arms dropped over Britain to continue to let his family know he alive. The commandant again grants the request.
Another month goes by and the pilot again asks if he can have his other arm dropped off. The commondant replies "NEIN". The Brit asks why? The commandants reply: "We think you are trying to escape".
