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 held them at gunpoint and made them stand at attention, turning their heads from side to side and saying, "Tick - Tock", over and over.
After about three hours, one of the pilots 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 that vee haf vays of making you TOCK!"
