Three Spies are captured in London. One is German, one is French and the other is Italian.

First they interrogate the German spy and after 3 hours of torture he talks and is thrown back into the cell with the others.

Then the French spy is interrogated, and after about 8 hours of torture they get him to talk and throw him back with the others.

Last they interrogate the Italian spy and after 20 hours of torture and failing to make him say a word they give up for the day and throw him back with the others. When he is back in the cell with the other spies asked him,

"how did you last that long without saying a word"? Then the Italian man says, "I was trying to speak but they had my hands strapped down and I wasn't able to move them".
