Phone rang
caller ID:  "mary smith"
Me: "hello"
Guy: Is this (had my name)?
Me: (can't remember if I answered, but I did ask "is this mary smith?"
pause
Guy:  "oh boy"  more like a sigh.

nothing more

Received this call on a business phone.  Dead silence then "Goodbye" as if I had been leaving a message on a recorder.  Next time I let it go to the answering machine and it did the same thing.

Phone rang.
Me: Hello.
Caller: Can I speak to Todd(not my name)?
Me: No.
Caller: Why?! Are you a dummy?!
       - Caller immediately hung up after saying this, which was the smartest thing he could have done because I love to verbally abuse these people. Its fun. 'Im not shy about it either. I'll go low right from the start, spewing nasty, racial, profanity laden epitaphs. Now Ive got his number in my auto dialer along with many others. Now he'll get hundreds of hang up phone calls from me, every day, until I decide to stop them. Haha. I love technology.

I had the same thing happen as toponas

I got a call from the number and when I said hello, the woman said goodbye
