I believe Chip Clinton passed away in 2009, possibly even during the season. I may have that wrong.
He was downright funny at times with his heckling, and it wasn't just "Throw it in the Dirt", though that one is the one that gained the most fame. He had a voice too that you couldn't duplicate. He could yell for 9 innings from his seat at the top of the stands behind 3rd base, and you could hear him clearly out in right field. The guy was born to heckle.
I do agree though that the Throw it in the Dirt stuff has gotten out of hand now that he's no longer around to be the de facto heckle coordinator. The people that do it don't have the wit or the timing.
