How can a wrong number be so right?

This morning I got a call from a phone number with a San Antonio area code.

The conversation went like this:

Matt: Hello, this is Matt Dick

Slow, Slurred-Speech Guy: Hello?

Matt: Hello, this is Matt Dick

SSSG: <silence>

Matt: Hello?

Someone in the same room as SSSG: <something loud and unintelligible>

SSSG: Is this Mesario?

Matt: No.

SiSraSSSG: <something loud, unintelligible that is clearly a question>

SSSG (to SiSraSSSG): Mother fucker!  No, this is my friend's phone
number but some
little bitch answered!  What the fuck!?

SiSraSSSG: <much louder and unintelligible>

Matt: <hung up>

I *really* made a mistake and didn't string this along.  I'm thinking
of calling back and re-engaging...
