Sometimes a bar hits you over the head with its douchiness. Professor Thom's isn't one of those places. The UMass hordes that congregate here seem congenial enough at first.

You're in a Boston bar, and these people you formerly considered your new drinking buddies are actually Sox fans! Abort mission—we repeat, abort mission!
