Never let you cell phone out of your sight

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. I can hardly hear you.........are you at the club?"

MAN: "Yes"

WOMAN: "I'm at the mall now and found this beautiful leather coat.

MAN: "Sure......go ahead if you like it that much."

WOMAN: "I also stopped by the Mercedes dealership and saw the new 2006 models. I saw one I really liked"

MAN: "How much?"

WOMAN: "$90,000"

MAN: "OK, but for that price I want it with all the options."

WOMAN: "Great! Oh, and one more thing. The house I wanted last year is back on the market. They're asking $950,000"

MAN: "Well, then go ahead and give them an offer of $900,000. They will probably take it. If not, we can go the extra 50 thousand. It's really a pretty good price."

WOMAN: "OK. I'll see you later! I love you so much!!"

MAN: "Bye! I love you, too."

The man hangs up. The other men in the locker room are staring at him in astonishment, mouths agape.

He smiles and asks: "Does anyone know whose phone this is”?
