There were three American pilots captured by Germans in WWII. The Germans thought up a way to make the pilots crack and tell what they knew. They made them stand at attention, turn their heads from side to side and say, Tick - Tock over and over. After about three hours, the first pilot cracked and started telling all he knew, signing everything they put in front of him. An hour later, the second pilot cracked and started confessing to things that he didn't even do. The third pilot was fighting hard not to crack. He was about half-way cracked. He was turning his head to one side only and saying, Tick...Tick...Tick... The German officer in charge went up to him and said, You thinks you iss so schmart! But I'm telling you dot vee haf vays to make you TOCK!
