Ring the Bell

Passing an office building late one night, a blonde saw a sign that said, "Press bell for night watchman."

She did so, and after several minutes she heard the watchman coming down the stairs. The uniformed man proceeded to unlock first one gate, then another, shut down the alarm system, and finally made his way to the door.

"Well," he huffed, "what do you want?"

With hands on hips she said, "So, like, why can't you ring the bell yourself?"
