Please help translate a little joke. It's very simple.

There was a young boss who had just started his career and was sitting in an elegant office. He saw someone coming into the outer office. In order to show that he was busy, he picked up the phone and pretended to be doing a lot of things. He made exaggerated gestures and spoke loudly. Finally, he hung up the phone and asked the caller: "What can I do for you?" The caller replied: "Of course! I'm here to fix the phone!"
