My favorite ones are the ones that just become part of the game. The ones I still catch myself thinking or we used to say on the field ourselves.
Gas. He Gone.
Can of corn.
Stretch.
Get on back there/WAY back.
PIOTB Yeee---Yes YES.
My favorite however, came from a late Frank HR in maybe 2003/2004 against the Twins. "WAY BACK, DEEP AND INTO THE NIGHT! YOU CAN PUT IT ON THE BOAAARD." It was perfect, one of those hot late July/August nights and it was an absolute bomb. I was about 13 or 14 and the way he said deep and into the night was almost cinematic. He never said it again but it's burned into my brain.
Those are just the big ones, I'm sure if I sat with my thoughts there'd be about 50 more. Hell, there's some that only existed for a season or two that would pop in all of our heads in no time. But these ones were simple and they became a part of the game in our own lives. That's beauty. That's what made him so great. Sure he was a bit of an idiot but the ability to find a few words that leaked into every part of your thinking about the game is what made him a genius. I sincerely believe that despite his failings as a commentator he deserves EVERY bit of being in the Hall of Fame. Surprisingly enough, I find I'm missing him more and more. And that's no disrespect to Bennetti, I think he is becoming a great voice in his own right.
