Hawk is almost the Bill Walton of baseball, except he has the awesome cliche of "Hegone!" He's annoying as hell if you take him seriously, but if you just keep in mind that he's an absolute idiot, you learn to laugh at everything he says. In addition, his voice is nearly comedic. His clear White Sox bias makes everything even funnier.
I saw a lot of the White Sox on MLB TV last year. I learned to lmfao at Hawk Harelson.
This is also why I now very much enjoy Sunday Night Football. They're the Beavis and Butthead of commentators. I really hate Chris Berman, though. I love the NFL Draft and even then I was having trouble standing him on Day 1. His sad attempts to slap nicknames on EVERY DAMN player is absolutely sickening. Easily the worst commentator in the mainstream. Thank God that Suzy Kolber took over on Day 2...or else I would've thrown the remote at the TV in good time.
