From a game you were at, or even just seen on TV.
My favorite for a game I attended was the division clincher last year.
One of my wildest memories was June 30, 2006 Indians @ Reds game. Reds were down 7-1 late and dad (first game) was complaining and wanted to leave. I argued him not to since I am die hard baseball fan and cant stand leaving early. He said he was leaving and unless I wanted a ride back to Columbus. We got to about Kings Island and Dunn hit the walk off grand slam off Wickman and I damn near pushed him out of the car. He has never left a game early since.
