Funny call on cell phone

Today's funny:

I got an interesting call on my cell phone this morning and thought I'd share. Here's how it went:

Me: Hello
Caller: Hi, how are you
Me: Okay
Caller: Where are you?
Me: At home
Caller: What are you doing there?
Me: Where else would I be?
Caller: Not going to work?
Me: I don't work any more, I'm retired.
Caller: Oh my, sorry, I think I have the wrong number
Me: I guess you do!

Never did get that guy's name! Strange that he doesn't know what his wife (or his friend) sounds like on the phone!
