Sitting Around The Locker Room

Several men are sitting around the locker room of a golf club when a mobile phone rings.  One of the men picks it up, and the following conversation ensues:

Husband - "Hello?"
Wife - "Honey, it's me. Are you at the club?"

Husband - "Yes, I am"
Wife - "Great!  I'm at the mall two blocks from where you are and I'm looking at a beautiful leather coat. It's absolutely gorgeous! Can I buy it?"

Husband - "What's the price?"
Wife - "Only $1,000."

Husband - "Well, OK, go ahead and get it, if you like it that much."
Wife - "I also stopped by the Mercedes dealer and saw the 2015 models. I saw one I really liked. I spoke with the salesman and he gave me a really good price...and since we need to exchange the BMW that we bought last year..."

Husband - "What price did he quote you?"
Wife - "Only $60,000"

Husband - "OK, but for that price I want it with all the options."
Wife - "Great!  But before we hang up, just one more thing..."

Husband - "What?"
Wife - "I happened to stop by the real estate agent's office this morning and saw the house we had looked at last year for sale. The one with a pool, English garden and an acre of park area. The beach front property."

Husband - "How much are they asking?"
Wife - "Only $450,000.00 a terrific price...and I see that we have that much in the bank to cover it" 

Husband - "Well, then go ahead and buy it, but just bid up to $420,000.00 OK?"
Wife - "OK, sweetie...Thanks!  I'll see you later,  I love you!"
Husband - "Bye...I love you too."

The man hangs up and closes the phone's flap.  The other men are looking at him in astonishment. The husband raises his hand while holding the phone and asks "Does anyone know who this phone belongs to?"
