I don't really understand the rationale some sports fans have, especially when it involves a rival team winning a championship.

Walked in to work this morning to hear two coworkers expressing how they felt the Super Bowl was "terrible because the Packers won". How in the world does that make any sense? The game itself was one of the more exciting SB's I have seen in awhile. Are Bear fans really that impressionable that even the idea of Green Bay success is enough to piss them off?

What am I missing here?
