A young man is wandering around the zoo looking at the animals. He suddenly remembers about an appointment that he scheduled. Unfortunately, he forgets his watch. He searchs for someone who could give him the time. He sees a zoo keeper standing next to an elephant. "Excuse me sir," says the young man "do you know what time it is?" The zoo keeper reaches under the elephant, grabs his balls and starts playing with them. "Mmmmm, it is about 3:00" the zoo keeper responds. The young man looks at him in awe, "How did you know that?" The zoo keeper looks back at the man, "I looked at the clock on the wall right behind you."
