Tick Tock, Tick Tock...
Tick Tock, Tick Tock... Colonel Reichman, an interrogation specialist for the German army, was walking around in a quaint little Swiss village one day during WWII. He spots a little shop selling clocks and watches and decides to enter. Inside, the owner, a lady standing behind the counter, immediately recognizes who he is and welcomes him into the shop, asking how she can be of assistance. "Frauline,” he starts "Deez are all very nice little clocks and vatches you have in here, but ze von I am interested in is zat big grandfazer clock you have outside above your door.” “Nein colonel, I am sorry, but zat grandfazer clock is not for sale.
