Mark's Secret Admirer

I received this voicemail on my cell phone today. I didn't answer, as I was running at the time. I have no idea who this person is, even after doing a reverse phone number lookup. I can only assume it's a wrong number, but would you all watch my back, just in case?

By the way, in the process of figuring out how to get this on my blog, I found audioblogger. You can post voice blogs from any phone. Pretty cool.
