Bell Humor

Late one night, an airhead saw a sign on an office building. It said: "Press bell for night watchman." So the airhead pressed the bell. After several minutes the night watchman could be heard clomping down the stairs. He unlocked the gate, shut down the alarm system, and finally made his way through the revolving door. "Well," he snarled at the airhead, "what do you want?" "I just wanted to know why you can't press the bell yourself."
