Three western spies are captured in the USSR

Three western spies are captured in the USSR. An English spy, a French spy and an Italian spy.

First they interrogate the English spy but he refuses to speak. So they tie him up, torture him for a day and in the end he speaks.

The same thing happened with the French spy. Initially he wouldn't speak but after being tied up and tortured, he speaks.

But then came the Italian spy. He refused to speak and after being tied up and tortured for weeks, he still wouldn't speak. Admiring his bravery, the Soviets decided to let him go. Before letting him go, an officer asks him: "How did you endure all this torture and didn't speak?". To which the Italian replies: "I tried to, but my hands were tied"
