It's a prank website. People can put in your number to be called and even chose the outgoing number. There's lots of different "themes" too.

I got the same exact call yesterday that  Elaine did. The name that came up on the caller I'd was John D and B Hyde.  It was comical and the guy kept calling me a b......So I handed it to my husband and e guy tried to argue with him, then gave up and hung up.  I didn't give him the information he wanted.

It's some guy calling, and yelling "you left a not on my car!  Man, why did you hit my car? What's your insurance information?"   Actually it's kind of comical. I started laughing.  I think they want you to get upset and start yelling at them or worse get defensive and give them personal information!  DO NOT EVER DO THAT!    So I just ask him to "back up a second, stop yelling, now where did you say this happened?"  Dumbass starts going off again yelling about his car.  I said "well if I left a note on your car what's my name?"  No answer.......I also got this same guy calling me on my cell this past Sunday night (4/1/12) spoofing behind my work number.  Same exact conversation, just kept yelling about his car, you left a note, bla bla bla.   Spoofers commonly use disconected numbers obviously so you can't call them back.  But this guy is laughable, not very sophisicticated and has a very limited vocabulary.
