I almost walked out on history yesterday.  With the A's v. Rays game about to start, I contemplated leaving early, since all my official duties were done for the day, and going home to relax.  Fortunately, I decided to stay at the game, and witnessed something that has only occurred 18 other times in the 120+ year history of Major League Baseball: a perfect game. 

This got my friends thinking: just how rare IS it to witness a feat of this nature?  According to one, there is a 1 in 13,000 chance that you'd see a perfect game when go out for a day at the ballpark.  More people have orbited the moon than pitched a perfect game.   There have been more presidents than perfect game pitchers.

The circumstances of the game were incredible as well, summarized here in the Chronicle.  Dallas Braden, who lost his mother to cancer, had his grandmother in attendance for Mother's Day.  As soon as the final out was recorded, she came rushing down the aisle toward the dugout, with all the fans in the area helping her towards the field.  When she got there, she ran to Dallas, and they embraced for several minutes, causing even the most cynical among us to choke up a little.  Braden is also a proud son of the 209, the Central Valley area code from which I also hail.  Braden still lives in his hometown of Stockton, and does an incredible amount of community work there.  In summary, this couldn't have happened to a nicer guy, or at a more perfect time.

Question for discussion: what is the coolest/rarest event you've ever witnessed, sporting or otherwise?  Something that made you say "Wow, I can't believe I just saw that!"
