We had a conversation a couple months ago about announcers jinxing no-hitters.
Fire Joe Morgan has a good post about Michael Kay jinxing a no-hitter then going completely insane when a caller to his radio show accuses him of the jinx. Fire Joe Morgan has a .wav file to listen to. It's hilarious.
I highly recommend listening to it. Because it's not often you can hear a respected broadcaster comparing silly baseball traditions to both the United States's sorry history of slave-owning and the Axis's horrifying history of genocide, all in a shrill New York accent.
