Who is this person, Mike, everyone tells me?

In past one week I am getting many emails about and form Mike, but I don't even know this Mike. Here are just some

* Mike recommends you for specialist
* Call Mike, he's waiting
* Remember Mike? He invites us to party!
* Please, talk to Mike
* Mike insisted on the talk
* Mike says he wants you to come
* Famous Mike wants us there
* Is it you? Mike here
* Give me Mike's number (Ed. note: added 3/12)

I will report again if moer emails come about from him.
