An employee of a store went up to his manager and said, "can I go to Paris for a week"? "Yes," said the manager "but remember to show me a picture of you at Paris" "yes sir," said the employee. The next day the employee showed him a picture of him in Paris, he saw a clock a big tv and him on the couch. Right away he knew that he had lied. How did he know?
The clock was showing the same time as the clock that was sitting on the manager's wall.
