Perhaps the most riveting video so far of the 2012 Washington Nationals season? See above: Davey Johnson reacts to a fire alarm during his pregame press conference before Tuesday's Nationals-Astros game at Nationals Park (link to CSN Washington.com video here). Okay, maybe "reacts" isn't the right way to describe it.
Interestingly, Davey reacted the same way in the 9th inning Tuesday night with Brad Lidge on the mound holding a 1-0 lead. But it all worked out.
