Morning Inspection at a POW camp

This joke needs an accent and some body motions for full effect. (I included them in parenthesis)

At a German POW Camp the Commanding officer inspects the prisoners each morning in a line up. One Day as he's going down the line he gets to the final three prisoners and inspects them.

The first prisoner is jerking his head side to side, and as his head goes back and forth, he makes peculiar sounds.

"Tick (head jerks left), Tock (head jerks right), Tick , Tock"

The general makes note of this behavior in his journal, nods his head, and continues to walk down the line.

He aproaches the next prisoner. As he stands in front of him, the prisoner is doing the exact same motions, with the same weird noises.

"Tick (head jerks left), Tock (head jerks right), Tick , Tock"

The general nods his head again, writes in his journal, and goes to the next prisoner.

As he looks over the last prisoner, he too is making weird noises and movements.

"Tic (head jerks left), Tic (head Jerks Left), Tic (head jerks left)."

The commanding officer scowls as he looks at the POW. He grabs him by the throat and says,

"Ah, a stubborn one? No worries, we have ways of making you tock."
