The only reason I remember NOOK is because it resulted in one of my favorite broadcast moments in Nationals history. I can't remember what game, but it was in 2007 and Nook hit a deep fly ball. Bob Carpenter suddenly got excited and exclaimed "IS THAT A HOME RUN FOR NOOK"?!?!?!?!?!
It was caught at the warning track. No idea why it was funny to me but I died laughing after it was caught.
