Mouse Trap

My brother Jim was hired by a government agency and assigned to a small office cubicle in a large area. At the end of his first day, he realized he couldn’t see over the panels to find his way out, so he waited until he saw someone else leaving and followed him. He did the same the next day. On the third day he had to work late, long after his colleagues had left. He wandered around lost in the maze of cubicles and corridors, but then, just as panic began to set in, he came upon another employee in a cubicle.

"How do you get out of here?" Jim asked.

The fellow looked up from his desk, smiled and said, "No cheese for you."
