Inmate escapes German jail in box
This reminds me of the joke from Memphis Bell about the pilot shot down over German territory during the second world war. He manages to bail out with his parachute but breaks both of his legs in the fall. In the POW camp, the German doctors inform him that one of his legs must be amputated. He asks if they can drop his leg in a friendly base on a bombing run, to which they agree. A week later he needs the other leg chopped off, and similarly makes the same request which they honour. Another week passes and he has to get his arm amputated, once more asking it to be dropped off in England. This time the doctor returns: 'Nein! Dis vee can do no more!" The POW asks why... "Vee think you are trying to escape!"
I love jokes you dad would find funny!
