I've come to install the phone
A young businessman rented a beautiful office and furnished it with antiques. However, no business was coming in. Sitting there, worrying, he saw a man come into the outer office. Wanting to look busy, he picked up the phone and pretended he was negotiating a big deal. He spoke loudly about big figures and huge commitments. Finally, he put down the phone and asked the visitor "Can I help you?"
The man said, "I've come to install the phone."
