Anyone have any idea what Brian's big surprise is?

That he's really a military commando on a covert mission to spy on computer dweebs.

Everyone knows that Brian is really... Wait! If I told you, I'd have to kill you.

We can speculate forever, but without some information from which to draw a conclusion, speculation is pointless. When I joined this group, I accepted the group's aims. In this case, it means assuming that BriDog72 and BatFan73 are going to do something significant. Until they post what that is, we should be patient.
