"Locker Room Phone call" joke

Several men are in the locker room of a golf club.
A cell phone on a bench rings and a man engages the hands free speaker-function and begins to talk. Everyone else in the room stops to listen.

MAN: "Hello"
WOMAN: "Honey, it's me. Are you at the club?"
MAN: "Yes"
WOMAN: "I am at the mall now and found this beautiful leather coat. It's only $1, 000. Is it OK if I buy it?"
MAN: "Sure,. .. go ahead if you like it that much."
WOMAN: "I also stopped by the Mercedes dealership and saw the new 2003 models. I saw one I really liked."
MAN: "How much?"
WOMAN: "$60, 000"
MAN: "OK, but for that price I want it with all the options."
WOMAN: "Great! Oh, and one more thing. The house we wanted last year is back on the market. They're asking $950, 000."
MAN: "Well, then go ahead and give them an offer, but just offer 900, 000."
WOMAN: "OK. I'll see you later! I love you!"
MAN: "Bye, I love you, too."

The man hangs up. The other men in the locker room are looking at him in astonishment.

Then he asks: "Anyone know who this phone belongs to?"
